Internet Links

Following are links to Internet resources that can be used to support instruction of the Math World feature for this chapter.

A Fractals Lesson
Want to know more about fractals? This site is a good place to start because it was created for elementary and middle school students. Fractals can be a complicated high-level mathematics subject, but you'll find them explained here very simply.

The Math Forum: Doctor Math: Lattice Multiplication
This is just one of hundreds of math questions answered by Dr. Math at the Math Forum site of Swarthmore College. This page offers a good explanation of solving multiplication problems with the lattice method. This site is a wonderful resource for both students and teachers. Take some time to look around or ask a question.
