## Great Geoboard Activities for Guided Math Groups

Geoboards are a great manipulative. They come in a square frame and a circle frame. You can either buy them or make your own. You use them with rubberbands/geobands. Always discuss the proper use of rubber bands and have consequences for folks who use them inappropriately. Be sure to give the students free exploration time before you give an assignment (as with any manipulative). Also be sure to have the students transfer designs back and forth between the actual geoboards (concrete level activities) and the dot paper geoboards (pictorial level activities). You can use geoboard to explore many different geometry concepts such as classify polygons, estimate and calculate the area and perimeter of a polygon, construct line segments and endpoints, draw congruent figures, explore angles and do coordinate grid work. Below I have listed a couple of great links to geoboard activities.

** **

**Making Shapes**

- Use your geoboard to make different shapes: polygon, quadrilateral, triangle, square, rectangle, pentagon, hexagon and an octagon.
- Use interactive geoboards to explore geometric shapes, describe their properties and develop spatial sense.
