Instructions for Use
Geoboard prompts your child to investigate different units to measure area.
To use Geoboard, select a circle by holding the mouse button down, and drag it to any location on the gird. Release the circle toanchor it. A red node appears at the top of the circle.
Click on any part of the circle and drag it in any direction. It will stretch much like a rubber band. Secure the band to any points on the grid. You can make squares, triangles, rectangles and many other geometrical shapes.
Click on the circle again to add as many bands as you like. To color the area in the shape, click first on the shape and then on the color buttons to the right. To release a node, hold the Ctrl key down and click on the node.
