What is multiplication? Your children's experience with multiplication will depend on the answer (or several) you have to this question. It will also determine where you will look for examples of multiplication - multiplication tables, a mirror, your child’s drawings, a stroll around your neighborhood… And researchers suspect that early experiences with multiplication (or lack of them) largely determine the future success with all math and science. That's because multiplication is the cornerstone of algebra.
How will learning these critical concepts fit your and your children's day-to-day activities? And how will it help enrich your and your children's relationship with mathematics? We will discuss these and other questions in our upcoming Math Cafe.

I did a variation of this paper activity with kids last week - it's about RECTANGLES. The shape itself is not creepy or weird or exciting in any way. The idiom for the opposite of cool is "square." http://fractalfoundation.org/resources/fractivities/fractal-cutout/
Yet kids said "this is weird" or "this is creepy" too. They think fractal cows, "gentle cows," in the animated short "cows and cows and cows" are very creepy. cows & cows & cows
We are onto something here. With a fractal, the IDEA of infinity or infinitesimals becomes tangible so strongly and quickly, you get some of the "total perspective vortex" mood whiplash from it.Cheers,

To some of us, writing computer programs is a fascinating game. A program is a building of thought. It is costless to build, weightless, growing easily under our typing hands. If we get carried away, its size and complexity will grow out of control, confusing even the one who created it. This is the main problem of programming. It is why so much of today's software tends to crash, fail, screw up.
When a program works, it is beautiful. The art of programming is the skill of controlling complexity. The great program is subdued, made simple in its complexity.

Love the RECTANGLES activity!The other powerful ideas within fractals are:Self Similarity, iteration and how a simple set of instructions repeated over and over can lead to beautiful and amazing things!!!
Also the weirdness helps the concepts stick in the kids minds. I think that's why they always seem to remember me;)
