Geoboard

About this app

Digital geoboard with 5×5 pegs: stretch elastic rubber bands in different colours and build shapes like a house, kite or star. Analysis tools number corners and sides, tint the area square by square and test symmetry with a mirror band. The number trap refutes the misconception that equally long bands enclose equally large areas: perimeter 10 can mean 4 or 6 squares.
