Geoboard - Educational Geometry Board

Geoboard

From Wikipedia, the free encyclopedia

A geoboard is a mathematical manipulative used to explore basic concepts in plane geometry such as perimeter, area and the characteristics of triangles and other polygons. It consists of a physical board with a certain number of nails half driven in, around which are wrapped geo bands that are made of rubber. Normal rubber bands can also be used.

Geoboards were invented and popularized in the 1950s by Egyptian mathematician Caleb Gattegno (1911-1988).

Hint 1: To prevent warping, I recommend using the version with discs aka mouse ears.

Hint 2: If you have problems with bed adhesion when printing the pins, add a brim.
