**Instructions for Use**

**Interactive Geoboard:** This activity allows students to begin to count the distance around objects to develop an understanding of perimeter.

Choose a “rubber band” and click and drag with your mouse to stretch it across the Geoboard. Create a rectangle with your rubber band. Now start at one corner and count the number of units that go around your rectangle. A unit is the length between two of the red dots.
