Miles (6), who is homeschooled, finished his 1st Grade math curriculum today. He was very proud of himself.

1) The above is called Pascal's triangle
2) The number of rows is infinite (although you'll get tired of calculating rows).
3) To make a new row, add two consecutive numbers in a row and put the sum between the numbers, on a new row below. Eg. 5+10 is 15.
4) The top number is 1 (not shown) and is in row 0.
5) If you ever care to expand (x+y)^n (n is an integer), the coefficient of the terms in this expansion can be found in row n. Eg. (x+y)^3 = x^3 + 3(x^2)y + 3xy^2 + y^3 see? 1,3,3,1, which is row 3. This is also called the binomial expansion (bi since there are two terms, x and y)
6) Suppose you need to know how many different groups of 2 people can be made using 4 people. We can see that the groups would be persons: 1&2, 1&3, 1&4, 2&3, 2&4, 3&4, so 6 groups. Now that was easy with only 4 people, but suppose you had 20 people and needed to figure out how many groups of 5 could be created. You don't want to do this by hand! The mathematical term for what we want is called a combination: the number of groups of size r that can be formed using n objects, or nCr. Going back to the original example, look in the 4th row (n = 4) and in the 2nd diagonal (r = 2, where diagonal r=0 is the diagonal of 1s). We find 6!
7) Since nCr = nC(n-r), the triangle is symmetric. Eg. Using 3 people, there are 3 groups of size 1 (r=1)and 3 groups of size 2 (r=2), so 3C1 = 3C(3-2) = 3C1. The actual definition of a combination is nCr =n!/(r!*(n-r)!), where n! = n*(n-1)*(n-2)*...*2*1. The "!" is called "factorial". Eg. 5! = 5*4*3*2*1 = 120. You can do this computation on a calculator, so you don't need the whole triangle to calculate 20C5.
8) The sum of the numbers in a row is a power of 2. Eg 1+5+10+10+5+1 = 32 = 2^5, which were the digits of row 5 in the table.
9) Pascal's triangle is really easy for high-schoolers to learn, and thus they can expand (x+y)^n easier than normal.
Isn't math great?
You can see my dislexia in full swing here. This is the "corrected" version of course. Sad part is I was already 8! (1988) It took me a while, but I would like to belive I picked up steam after that ;-p

We are navigating through uncharted waters with this new way of learning Math. Math U See is a slower paced yet (for us) a more logical way of learning Math concepts. It's also great for kinesthetic (touch and feel) and visual learners since it involves the senses in the learning process.
Math Presentation Guest Speaker
During the recent math convention I went to, one of the main speakers was Eric Demaine, so I couldn't miss seeing that. And yes, that is my Alphabet in his powerpoint presentation- he liked my work so much, he added a few photos to his slides. :-D

Math in a Bag activity. The child chooses 2 drawers of objects and uses them to show the equation on the card.
At Casey Elementary School on Camp Casey Jan. 14, students and parents take part in the school's second annual Math Madness workshop, which aimed to build math proficiency by using games and other activities to make the subject enjoyable for youngsters. In one of those activities, for example, competing groups had to use 20 strands of uncooked spaghetti and about a yard of masking tape to create the tallest possible structure that would support a marshmallow for at least 30 seconds without collapsing. - U.S. Army photo by Pfc.
