23cm square Geoboard.
Double sided with an 11 x 11 pin grid array on one side and an 11 x 11 triangular pin grid on the other.
This is for one Geoboard only with one pack of 20 rubber bands. The rubber bands are in various sizes and colours.
Both of my children enjoy using the Geoboard. The work photographed here is by Otis (at 35 months) and Caspar (at six years). Geoboards are commonly present in the 3-6 and 6-9 Montessori classrooms.
