Homemade geoboard

The Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around pegs to form line segments and polygons 
Geoboards offer opportunities for hands-on exploration of geometric concepts, including shapes, symmetry, congruency, area, perimeter, coordinates and spatial relationships.

An homemade geoboard is quite simple ti do. Take a wooden cutting board and some nails. Paint your cutting board and plant the nails following the geometric pattern that you have drawn first on the chopping board. Put rubber bands ...and play
