A New Learning Adventure!

3X School starts today for my "triplet" 17 year old high schoolers. Yes I said "triplet". This week we gained guardianship of a friend of Jacey's so my twins now have another sister! She spent the summer with us and I watched everyone grow as a result. Now we all have the opportunity to grow and learn even more. I plan to journal our journey over this next year, so stay tuned. She is our second daughter through guardianship. We learned and grew so much with our first guardian daughter - I am excited about what this next year and on will enable me to learn. Join me in the journey. Happy First Day of School!

LSAT Prep Book Recommendations

Here's the moment you've all been waiting for: my LSAT prep book recommendations.

Happy holidays to everyone. There WILL be more tips next week too, don't worry - not everyone is on vacation. :D Recommendations below. Stay warm!

PrepTests 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, and 56
by LSAC

Each are only sold individually, as LSAC has not yet published a book of ten exams containing them. Because the exam has changed in recent years, you'll need several of these to study effectively.

When to use: after you've completed the other PrepTests.

The Next 10 Actual, Official LSAT PrepTests
by LSAC (older edition)

Contains PrepTests 29-38 and is the newest book of ten. It's essential that you get your hands on these in order to study effectively.

When to use: during exam prep.

10 More Actual, Official LSAT PrepTests
by LSAC (older edition)

Contains PrepTests 19-28.

When to use: during exam prep.

10 Actual Official LSAT PrepTests< br />by LSAC (older edition)

Contains most PrepTests from 7-18. Only worth doing if you're studying far enough in advance that you'll have enough time to do the most recent exams as well.

Note: These exams are really old - from 12/92 - 9/95. Don't be concerned if some of the games are a bit difficult. You'll rarely see these types on recent exams.

When to use (if at all): in early stages of preparation to familiarize yourself with the exam.

The Official LSAT SuperPrep
by LSAC (older edition)

Contains a few exams you can't find anywhere else: 2/96, 2/99, and 2/00. The explanations within are the biggest selling point, but most people find them to be confusing and technical.

When to use (if at all): in early stages of preparation.

June 2007 LSAT exam (PDF)
by LSAC

Free sample exam. Treat it as if it were PrepTest 52.5 when making your study schedule.

LSAT Logic Games Bible (2003)
by Powerscore (2008)

This book contains the best Logic Games diagramming techniques I've seen, and I've reviewed all the LSAT prep books out there. The drills are useful, the organization is clear, and the book demonstrates its techniques on real LSAT PrepTests.

Skip the section on "Pattern Games" and "The Forgotten Few" unless you've already mastered other game types. Also, don't worry too much about the book's complicated subclassifications. You'll be fine if you can distinguish between the main game-types: linear/sequencing, grouping, and combination.

Unless you have a lot of time, I recommend the 2003 edition. Why? Because the 2008 edition is nearly twice the size. It appears the author beefed it up to justify the $65 retail price tag. Also, the 2008 edition exposes you to recent games you'll want to save for later practice tests.

When to use: Before you attempt logic games from the books of PrepTests.

Logic Made Easy: How to Know When Language Deceives You
by Deborah Bennett (older edition)

Although not explicitly written for test-prep purposes, this book contains several logical reasoning-type questions and reviews several common fallacies. The author is clearly familiar with the LSAT, and this makes the book more relevant for our purposes. I highly recommend reading this because it is clear, full of simple examples, and concise. You can skip the parts on the history of logic.

American Scientist's review.
When to read: Before you begin LSAT prep or when you need! a break from practice exams.

Informal Logic: A Pragmatic Approach

by Douglas N. Walton (older edition)

Clearly explains and demonstrate multiple examples of valid and invalid arguments. Walton is obsessed with logical fallacies and covers many of the common ones appearing on the LSAT.

When to read: Before you begin studying or when you need! a break.

Elementary Logic: Revised Edition
by William V. Quine

At 144 pages, it's short and sweet. It's also the first-ever logic textbook (originally published 1941, revised 1980). It discusses many basic issues (necessary/sufficient, etc.) relevant to LSAT logic. If you have the time/inclination, feel free to look it up, but it's by no means necessary.

When to read: Before you begin studying or when you need a break.

How to Solve It: A New Aspect of Mathematical Method
by George Polya (Older editions)

Simple advice on problem solving and logical thinking. It's useful because it gives you a framework to identify and analyze the relationship between evidence and conclusion. Wikipedia, this summary, and the following will probably be enough for you.

The book gives you some questions to ask yourself about any Logic Game or Logical Reasoning Stimulus:

1. What information is unknown/provided? Does the evidence/premise satisfy the conclusion?
2. How is this game/stimulus similar to others you've done? Questions do tend to come back in future exams (with different topics, of course).
3. ! Does a restatement (the contrapositive) of the argument help?
4. What inferences can you make?
5. How can you use these inferences?

Another nice summary.

When to read it: Before you begin studying or when you need a break.

The Little Luxe Book of Sudoku: 335 Easy to Hard Puzzles and The Little Black Book of Sudoku: 400 Puzzles
by Will Shortz

Number puzzles exercise your brain and get it ready for the logic games.

When to use: Before you begin studying or when you need a break.

T! hat's it - see you next year!

Surds and the pursuit of happiness

My son Arthur mentioned that he had learned about surds in maths, so we asked him what one was. The definition I vaguely recalled from my school days was that a surd is an irrational number, but of course that's not the whole story, since it would seem that not every irrational number is a surd. Arthur did not know an exact definition, and it would seem that no-one else has tried very hard to pin it down precisely. Higher GCSE Mathematics for Edexcel by Alan Smith, p492, states:

Some quantities in mathematics can only be written exactly using a square root symbol.

For example, if x²=5, then the exact value of x is √5 (or -√5).

Quantities like these, written using roots, are called surds.

Based on discussions and exercises on the following pages, it appears that a number like 1+√2 is a "surd expression" rather than just a surd, but neither was it rule! d out as being a legitimate surd. The book gave no hint about whether, for example, the cube (as opposed to square) root of 2 is a surd.

Other sources are similarly imprecise. Wikipedia indicates that a surd in an N-th root (presumably, an N-th root of a positive integer, where N is also a positive integer). It says here that

An unresolved root, especially one using the radical symbol, is often referred to as a surd.

Based on the usage of the word in that web page (which also explains its origin) it looks like it's supposed to be a (real-valued) positive integer root of a positive integer.

This web page states the most restrictive definition: "A surd is a square root which cannot be reduced to a whole number." Pre! sumably they mean: a square root of a positive integer, and no! t a numb er like √(9/4) = 3/2. Wiktionary says: "An irrational number, especially one expressed using the √ symbol." (which would appear to allow 1+√2).

With a view to inducting my sons into the family trade, I thought that it would be a worthwhile mathematical exercise to discuss what should be the right definition. (The definition itself will not be interesting mathematically, but the pursuit of one is of great value; by analogy, the chap who coined the phrase "Life, liberty and the pursuit of happiness" clearly figured out that pursuit of happiness, rather than happiness itself, was the point.) It's a topic that touches on all sorts of issues, such as which if any, of the alternative definitions are equivalent, and why. More fundamentally, it addresses the issue of what constitutes a genuine mathematical definition, as opposed to some general guidelines on usage. Finally, the alternative definitions will! have various different merits, such as being a set of numbers that is closed under addition. In the event the discussions did not get very far, but looks like a good one to have in high school math lessons.

(added later: Mark Jerrum pointed out this link on mathematical terminology; in the case of surds, it contains more historical detail than wikipedia's page.)

Reading, writing and chewing gum

From the NY Post:

When does 2 + 2 = 5?

When you're taking the state math test.

Despite promises that the exams -- which determine whether students advance to the next grade -- would not be dumbed down this year, students got "partial credit" for wrong answers after failing to correctly add, subtract, multiply and divide. Some got credit for no answer at all.

"They were giving credit for blatantly ! wrong things," said an outraged Brooklyn teacher who was among those hired to score the fourth-grade test.

State education officials had vowed to "strengthen" and "increase the rigor" of both the questions and the scoring when about 1.2 million kids in grades 3 to 8 -- including 450,000 in New York City -- took English exams in April and math exams last month.

But scoring guides obtained by The Post reveal that kids get half-credit or more for showing fragments of work related to the problem -- even if they screw up the calculations or leave the answer blank.

Scorers joked about giving points to kids who wrote their names, brought a pencil or shared gum.

Math problems of the week: 1900's algebra vs. College Preparatory Mathematics

I. Two of the problems in the second chapter of Wentworth's New School Algebra, published in 1898 (written by G.A. Wentworth), p. 22:

Write in symbols:

A man has x dollars y dimes and z cents. If he spends a half-dollars and b quarters, how many cents has he left?

A rectangular floor is a feet long and b feet wide. In the middle of the floor there is a square carpet c feet on a side. How many square yards of the floor are bare?

II. Two of the problems in the final chapter of College Preparatory Mathematics Algebra Connections, Volume 1, (written by Leslie Dietiker, Evra Baldinger, Carlos Cabana, John Cooper, Mark! Cote, Joanne da Luz, David Gulick, Patricia King, Lara Lomac,! Bob Pet ersen, Ward Qincey, Babara Shreve, and Michael Titelbaum) p. 266:

Using the variable x, write an equation that has no solution. Explain how you know it has no solution.

Given the hypothesis that 2x + 3y = 6 and x = 0, what can you conclude? Justify your conclusion.

III. Extra Credit

The following is the final problem in CPM's Algebra Connections, Volume 1. Discuss.

HOW AM I THINK! ING?

This course focuses on five different Ways of Thinking: reverse thinking, justifying, generalizing, making connections, and applying and extending understanding These are some of the ways in which you think while trying to make sense of a concept of to solve a problem (even outside of math class). During the chapter, you have probably used each Way of Thinking multiple times without realizing it!

Review each of the Ways of Thinking that are described in the closure sections of Chapters 1 through 5. Then choose three of these Ways of Thinking that you remember using while working in this chapter. For each Way of Thinking that you choose, show and exlain where yo used it and how you used it. Describe why thinking in this way helped you solve a particular problem or understand something new. (For instance, explain why you wanted to generalize in this p! articula r case or why it was useful to see these particular connections). Be sure to include examples to demonstrate your thinking.

Linux Tip: Retrieving Files From Unbootable Windows partitions

You are a Windows person. You've been using Windows for your daily work, school, or something else. One day, you turn on your PC, and, for whatever reason, you can't boot your Windows. You try every trick you know without success. Your last resort is to recover your precious data from your unbootable Windows partition — if your hard drive is still in good condition and accessible. You could use a Windows Vista installation CD which lets you use the unfriendly Windows repair console.

You can also use Linux to retrieve files from your troublesome Windows partition. If you don't have Linux installed in your computer, you can use a Linux Live CD that's available free from the Internet. A live CD lets you try something without installing it into your computer. Most Linux installation CD's released today are also live CD's. For example, you can try an Ubuntu CD to test-drive Linux and also access data from your broken Windows partition.

Assuming that you booted into Linux, start xterm, konsole or Gnome terminal. Mount your Windows partition with the following command so that you can access and copy files from Windows — specify your Windows partition in place of /dev/sda1:

mount -t ntfs-3g /dev/sda1 /mnt

The command above mounts your Windows partion /dev/sda1 on the directory /mnt. Now, you can change the current directory to /mnt and list its contents like this:

cd /mnt
ls

Plug in your USB flash so you can save your data on it. Then, mount your USB flash onto /media &mdash assuming your flash drive is /dev/sdb1 and the directory /media exists:

mount -t vfat /dev/sdb1 /media

Now you're ready to copy files from your broken Windows partitions to your flash drive using Linux. The following example illustrates copying files in Linux:

cd Users/Kenneth/Documents
cp project7k.doc /media
mv finance9b.xls /media
tar cf - folderX | (cd /media; tar xf -)

The first command in the example above lets you change the current folder to Users/Kenneth/Documents — that's the typical path to user data in Windows Vista. The next commands copy the file project7k.doc and move finance9b.xls and folderX to your flash drive mounted on /media.

Once you retrieve your data files from the broken Windows partition and save them on your USB flash, you can go ahead and wipe your Windows. Then, you may choose to reinstall Windows, or better yet, try and install Linux. My recommendation is Debian Linux.

Add Fractions

In this blog we are going to learn about add fractions.

Fraction is a number that can represent part of a whole. The earlier fractions were reciprocals of integers: ancient symbols representing one part of one, one part of four, one part of four, and so on. "vulgar" fractions still used today And which consist of a numerator & a denominator.To get more knowledge on fractions than try to take help from online help with math.

Mathods how to Add Fractions –

They can write the fractions as

Example 1: 6 can be write as [6/1] or [12/2]

Example 2: 3 can be write as [3/1] or [ 24/8]

Example 3: 1 can be write as [1/1] or [7/7]

Example 4: 22 can be write as [22/1] or [66/3]

The examp! les show how to add the fractions.

The general formula to add the fraction is [a/b+c/d = (ad+bc)/(bd)] .

Next time we will solve some problems on add fractions.

Using a Multiplication Chart to find Equivalent Fractions

This is one of my favorite math tricks that can really help your students as they try to understand how to work with equivalent fractions. I learned it at a workshop a couple years ago and have yet to meet a teacher who previously used or was aware of how simple this chart is to help students.

Many simple equivalent fractions (most of the ones used in upper elementary years) are easy to find on a regular multiplication chart. I feel it is very helpful to point this out to your students. Many students struggle as they try to learn the many steps that it takes to find equivalent fractions. When you look left to! right on the chart you are viewing the multiples of a number. When you view two different rows of multiplies you are viewing equivalent fractions.

For example using the 1's and 2's. Look at the two rows as if they were fractions.
1/2 = 2/4 = 3/6 = 4/8 and so on. You can split rows apart. Look at the rows for 1's and 3's. 1/3 = 2/6 = 3/9 = 4/12 and so on. To show how the chart works with my class I use an overhead projector and circle the numbers to make them easy to locate. To find 1/5 = ? / 30 I circle the 1 and the 5 underneath it on the ones column on the chart. Then I move my finger from the 5 until I get to the number 30 and circle that. I can block out or just cross out other numbers to make it clearer. Then I follow the 1 across and the 30 up until they meet at the number 6. and circle that. If you do it correctly the circles will form a square or rectangle.

Of course, as the students understand how to work the chart, teach them the other ! ways of finding equivalent fractions. It makes it much easier ! for them , however, to "see" the equivalent fractions for a number and the students even start memorizing the most common equivalent fractions.

Now for the most important part. When students take a test they usually cannot use a printed multiplication chart. So what! Train them on how to make a multiplication chart from their facts and have them practice often. Then at test time, they can reproduce the chart onto their test before starting the work. It should take less than 5 minutes. Not only can they use the chart for checking fraction, but they can use it as they do multiplication and division problems too! No it is not cheating. It is about being smart, observant, and prepared!

Do play around with the chart on your own. I didn't believe it would work that simply until I practiced with it and used it with my class. There are some other tips and techniques that you can quickly figure out on your own that even make using the chart easier.

Here is a blank multiplication chart template.

It comes from this site which has a bunch of interesting math templates.

If your students have a hard time memorizing their multiplication facts then this book Memorize in Minutes: The Times Tables shows an easy and unique way to help them out.

Analyzing the Drop shape

The characteristic Drop shape [that appears when the ends of the saw blade touch each other] turned out to look rather different in the elastica version and the cornu spiral version. The latter is closer ! to the saw blade. With the help of grasshopper I plotted the curvature of the three curves above. The curvature of the elastica curve and the cornu spiral curve look as expected, but the curvature of the saw blade is a bit ambiguous and noisy. I probably need to redo the measurements.

Dynamical Systems - 8/4/10

Today, we were treated to a quick introduction to dynamical systems, an area of math which focuses on repeated iteration of maps to study long-term or asymptotic behavior associated with this iteration.

We started by taking a simple example. Consider a real valued function f from R to R. Then consider the sequence of points (x, f(x), f(f(x)) ....) We call this sequence the orbit of the point x.

Let us take f(x) = kx(1-x), which is the equation for a quadratic function. Also consider the identity map, g(x) = x.

For now, we take k >0.

Depending on our specific value of k, we have a parabola which intersects the g(x) either once or twice.

We are interested in the fixed points of f. As the name implies, these are points where the map f leaves a point in its domain fixed, or in symbols: f(x1) = x1.

We wish to study asymptotic behavior of functions. To do this, we! pick a point x on the real line and first apply the function. This gives us a new point f(x). Then we find f(f(x)). Since we have the identity map also drawn in (in this case, g(x)), this process is applying f, moving horizontally to g, moving vertically to f, and so on.

We see that repeating this process, we notice two general patterns: In some situations, we may continue onward towards positive or negative infinity in an unbounded fashion. However, for other sections of the real line, we see that there is a convergence towards certain fixed points.

We call a fixed point x attracting if the magnitude of its derivative at x is less than 1 and we say a fixed point is repelling if the magnitude of its derivative at x is greater than 1.

We see then that the derivative of the function at these fixed points greatly affects this convergence behavior.

Afterwa! rds, we moved on to dynamics of complex functions which map th! e comple x plane to itself.

We first took f: C -> C (complex plane to itself) given by f(z) = z^2 + c for some complex number c.

If we let c = 0, then points inside the unit disk spiral towards the origin. Points outside the unit disk spiral to infinity. We see that points on the unit circle itself get mapped to other points on the unit circle (their length is preserved, but they rotate.) Thus the mapping leaves the unit circle invariant. Furthermore, we see that iterates of the map can map a small section of the unit disk onto the whole unit disk.

We now consider the effect of varying our complex number c. For c very small, we obtain a similar picture: the interior of the curve spirals inward to the center, the curve itself is invariant, and the outer regions escape to infinity.

For very large x, most points escape outward to infinity.

We then construct the Mande! lbrot set as the set of points c such that the n-th iterate of the map f does not go to infinity when evaluated at the point c itself for technical reasons.

We take all parameters c and iterate at the point c itself.

Similar to our notion of fixed points, we say a point z in the complex plane is periodic with a period n if the n-th iterate of f applied at z = z.

We concluded by seeing various pictures of the Mandelbrot set and fractals constructed through similar dynamical systems in the complex plane.

arithmetic progression

Let us learn about arithmetic progression

An Arithmetic progression which consists of the sequence & the terms except the 1st can be obtained by adding 1 numbe! r to its preceding number. Arithmetic progression is denoted as the arrangement of 2 consecutive numbers, the progression which is constant. Sequence of numbers such that the difference of any 2 successive members of the sequence is a constant

If a, b, c are in A.P then prove that (a–c)² = 4(b² – ac)

Solution: a, b, c are in A.P

⇒ b – a = c – b = common difference

⇒ 2b = a + c

⇒ 4b² = a² + 2ac + c^{2 (}Squaring both sides)

⇒ 4b² – 4ac = a² – 2ac + c²( Subtracting 4ac on both sides)

⇒ 4(b²– ac) = (a – c)²( Taking 4 common)

Precalculus help

Introduction to study free calculus helps:-

Study free calculus helps involves the process of learning problems in calculus from free websites and also find calculus help free. Calculus is one of the parts of mathematics which deals with finding rate of the change of the given function with respect to change in the input function. Calculus is separated into differential calculus and integral calculus to find the rate of change. The following are the example problems in calculus to study with the helps of free websites.

Example 1:

Simplify the non linear function by differentiation.

f(s) = 2s³ – 5s⁶ + 7s

Solution:

The given function is

f(s) = 2s³ – 5s⁶ + 7s

Perform differentiation operation for the given function the solution to all your Math! problem

! f '(s) = 2(3s²) – 5(6s⁵ ) + 7

Solving the above terms we get,

f '(s) = 6s² – 30s⁵ + 7 is the answer.

Two Year Algebra - Reboot

Struggling students can succeed in Algebra and complete high school.

Approach

Organize a voluntary PLC of math teachers to pursue the pre-selected approach
Consider looping for ninth-tenth grade.
Use a reform math text - dramatically different from the district's standard text
Grade Summative Assessments on a curve of highest eighth = A, offset quartiles = B, C, D. If this is too drastic, then the PLC-advocated college grading scale of 75-100 is an A, 50-75 is a B, and 25-50 is a C may be appropriate.
Bottom eighth can earn a grade or pass by teachers's judgment or completion of alternative work such as ALEKS or StudyIsland or Algebra games like Dimension X/U or re-exam; even if semester has ended.
Bottom eighth cannot be determined until final for student motivation
Course starts with Assessment: Students scoring low that ALEKS Algebra Prep for Six Weeks
"Homework" completed in class as PRACTICE - careful attention paid to technique
Calculators used for most problems (some no calculator to mimic CST)
Supplements such as online formative assessment and/or Gizmos and/or Wolfram|Alpha or Akron.
Cultivate student growth mindset by using Brainology.
Experiment with DimensionU online math video game.

Possible Texts

Its About Time's Math Connections - not enough state standards may be an issue.
CPM - After 20 years, it now has state approval after changes - 1993 attack
Contract with Heymath! - other districts may have done this already.
Kinetic Books or NROC's new program, when available
Supplement current practice with a sequence of online manipulatives (eg Mathematica and Gizmos) coordinated with professional development and a PLC to determine sequence.

Suggested Calculators

Sharp WriteView
Casio Natural Display
TI/Casio Graphing Calculator, if text driven (Connections requires one)

Texts Review Status

More than one text can be selected depending on the number of teachers that volunteer and their interests.
CPM is used by 2-year Algebra programs where students alternate days of doing "homework" in class. CPM claims that no supplementary materials are needed. CPM, a non-profit, has an exceptionally low cost program:

August 2-6 - teacher training in Irvine at No Charge
Teacher text is $95 and each paperback, 3-hole punched, re-usable student text is $18
Classroom set of Algebra tiles is $97
2" loose-leaf binder for text and notes: $1 in volume

CPM has been used at Irvine's Northwood for six years. In one-year classes, CST proficiency has increased from 30% to 80%. In two-year classes, CST proficiency has increased from 6% to 24% and may be higher this year. The main reason Irvine adopted CPM was to give their students a different look at Algebra from the standard texts. CPM is also used by Northwood for Honors Geometry and Honors Algebra 2. I used CPM Geometry briefly at University High as a substitute. The question quality was quite high.
Heymath! has asked us to proceed. We would want to send them the Algebra AB pacing plan. The Massachusetts and Connecticut experiences show this can be fruitful.
For Kinetic Books: To track student progress through the Algebra text and do online homework, you will want copies for the individual students. This would be the Class Set License, which is $49.95 per student.
Putting a Computer Lab License on some of the computers at school would allow them to do online homework while at school, but you wouldn’t be able to track their progress through the book itself.
Online homework is $10.00 per student. Given your situation, I’m not sure you would be doing that on a regular basis.
Given the above you have a few choices:

If the Computer Lab License only, the students can use the text, but you don’t get any scoring information for them.
Use the Computer Lab License with online homework. With this you can track what the students do for homework that you assign.
Get Class Set Licenses for each of the students. This allows you to track their progress through the book and they can work at home.
The Class Set License plus online homework gives you the functionality tracking progress through the text as well as any homework you assign from the online homework system.
