9" Double-Sided 11 x 11 Pin Grid Geoboard

The largest and most versatile of our geoboards, the 11 x 11-pin grid side allows for a spacious four-quadrant grid to be created with a center origin, or use the subtle embossed numbers to work in one quadrant only. Use the staggered 3/4" isometric array on the opposite side to form shapes such as equilateral triangles or regular hexagons. Available in 6 assorted colors. Each board includes its own resealable bag of rubber bands in assorted colors. Colors may vary.
