## Interactive Math Software

GeoGebra is a software program designed to let students experience the natural connections between geometry and algebra (hence the name!) However, it should be noted that this resource extends down to the early primary grades—long before students enroll in an official class in geometry or algebra. It is now also possible to work on data and statistics as well as 3-D geometry in GeoGebra.

## Online Graphing Calculator

Desmos offers a free interactive calculator. At its simplest, it can be used as a four-function, scientific, or graphing calculator. Later, as students begin to encounter basic equations and more advanced algebra, the calculator offers many visual options for exploring math relationships. The calculator can be found here: https://www.desmos.com/

## Math Puzzles

Everyone gets bored doing repetitive drills of math problems. While procedures are important, it’s also a good idea to expose students to “real” math that involves creative thinking and problem solving. Here are some sites that offer a variety of math puzzles:

1. Stella’s Stunners (these puzzles officially begin at the pre-algebra level, but many do not require formal math knowledge to solve): http://ohiorc.org/for/math/stella/library/bycourse.aspx
2. Math is Fun Puzzles: http://www.mathsisfun.com/puzzles/
