For ages seven to adult. Rainbow Squares are another model designed for elementary, secondary, or adult students as an individual or collective learning puzzle. Six squares are each made up of three different rainbow colored pieces that can be put together in a variety of ways. Each of these pieces can also be used to form other squares using two, four, five, or six pieces that are easily constructed by younger children and recorded as colored shapes.
Older children can describe the area of each piece as a fraction or percentage of one square.
They can also make configurations of several pieces and copy the outline for other children to replicate like super Tangrams.
