Be warned groups can get very excited when playing this, so you will need to manage the behaviour well. S Math File Cabinet.

Index --- grids --- squares (examples) --- triangles (examples) --- Escher-style (examples) --- for teachers Triangles, squares and hexagons are the only regular shapes which tessellate by themselves.

I do the same thing for multiplication as well. Mathematical mysteries: Hailstone sequences. January 1997 This problem is easy to describe but it is one of mathematics' unsolved problems.

Starting with any positive integer n, form a sequence in the following way: If n is even, divide it by 2 to give n' = n/2. If n is odd, multiply it by 3 and add 1 to give n' = 3n + 1. Then take n' as the new starting number and repeat the process. Addition Trick. I must have been in about fourth or fifth grade.
