Teacher/mother Wendy Petti has created a wonderfully engaging and
visually striking site that brings mathematics to life through
math-related art, crafts, games, facts, and more. Math Cats will
probably appeal most to elementary and middle school students,
though some of its offerings will intrigue people of any age.
"Older Cats" (parents and teachers) will find a useful
idea bank of math activities and resources, as well as a
newsletter. Though Math Cats is not designed specifically for
girls, many girls are among its most enthusiastic audience.

If you have older children in math courses you can't help them
with, this site will be a godsend! There is a link for K-8 math
problems, but there are also tabs for algebra, geometry, trig,
and calculus as well as general math. This site will allow your
child to type in a math problem and will show them step by step
how to solve it.
