Yellow Triangles for Area & Stand for Height

The Yellow Triangles for Area provide children with a concrete way to explore the concept of area through manipulation and comparison of geometric shapes. Using uniform yellow square-based figures, children are able to build, decompose, and recombine shapes, supporting their understanding of how area is measured and how it can be represented visually and physically.

These materials are used together within the same work but are sold separately.
