The Equivalent Figure Material is an important component of the Montessori educational approach, designed to introduce children to the concept of equivalence that leads to the discovery of area and theorems.
By manipulating the pieces and observing their relationships, children can discover that shapes with different sizes can still be considered equivalent. This understanding lays the foundation for later mathematical concepts such as fractions, ratios, and proportions.
The Equivalent Figure Material consists of 13 green metal frames with bottoms and red insets.
