Created by an Egyptian mathematician, Geoboards are a fantastic tactile tool for learning early geometry/shapes, measurement, and numeracy concepts. The 9" board features 121 pins, arranged in an 11 x 11 pin grid. The 8” board contains 49 pins in a 7 x 7 grid, while the 6” and 7” boards have 25-pin grids. Flip over the geoboards, to see the pins configured as a circle. Depending on the board, these have different features. Rubber bands included or assorted rubber bands available separately. Optional activity cards for teaching inspiration.
