Instructions for Use

Area Explorer allows your child to demonstrate an understanding of area of regular and irregular shapes.

To use Area Explorer, look at the shape on the grid. Count how many squares are coloured and use that to determine what the shape’s area is. Type your answer into the white box and click “check answer” to see if it is correct. Click on “Draw New Shape” to see another shape on the grid. If you want to try working with a larger shape, increase the number for the shape’s perimeter.
