In this feature, we bring together activities which make use of a geoboard or pegboard. Geoboards are great for exploring shape and space, especially properties of shapes, area and angles.
A virtual geoboard that allows you to create shapes by stretching rubber bands between pegs on the board. Allows a variable number of pegs and variable grid geometry and includes a point labeller.
How would you move the bands on the pegboard to alter these shapes?
Choose the size of your pegboard and the shapes you can make. Can you work out the strategies needed to block your opponent?
How many different triangles can you make on a circular pegboard that has nine pegs?
