What Has
1½ Dimensions?
Fractal geometry is an intriguing new branch of mathematics. We've
all heard the buzz and seen the pretty pictures, but just what is a fractal
anyway? We'll explore the features of fractal objects, see that they are all
around us (and within us!), and come to understand the intriguing concept of
non-integral dimension. No fancy math needed – just an open mind
Why
Fibonacci?
We all love to show our students that the Fibonacci numbers occur
frequently in nature. True, it's really cool, but did you ever wonder why? That
insight combines elements of human perception, evolution, and the most

Ten
people seal their signatures inside identical envelopes, and then shuffle them.
You flex your psychic powers by trying to return each envelope to its owner.
WhatÕs the probability at least one person gets the right envelope back? In
tackling that question, weÕll encounter some interesting mathematics –
with 3 punchlines!
Financial
Planning with a TI
What
will my car payment be? How much do I still owe on my mortgage? How long before
I can retire? Use the TIÕs Finance App to teach your students (and yourself?)
