"Illustrated Lessons Math is the language of symbols. The way we work with numbers tells us a lot about their relationships, patterns, and the ways they change. Math helps us describe both similarities and differences and also helps us think and solve practical problems. In this section, you will find some fun ways to learn about math. You can start out with Estimation of Length, Place Value and Weight and Capacity. If you want something more challenging, take a look at Line Symmetry, Patterns and Tangrams.
