Geoboard is a free, open-ended maths app created by the Math Learning Center. Users stretch a series of five different colours of bands around pegs to explore mathematical concepts such as: lines, shapes, scale, angles, fractions, area, and a variety of basic geometry concepts. Bands are easily stretched around the virtual pegs with a “red light/green light” concept that even young children will understand. A green circle means the band can be successfully stretched around the peg while a red x means it’s pulled too far. Users can also fill in shapes by tapping on a ‘shape fill’ icon on the bottom docking menu. Shapes can also be easily erased from the board with a ‘refresh’ icon. Manipulative and entertaining, this app provides maths applicability across the age groups. Young children may need a bit of practice before the can stretch the bands correctly but will still get enjoyment out of the colours and the process.
Geoboard is suitable for Lower Primary, Upper Primary and Secondary.
