Decanomial Square & Instructions

The Montessori Decanomial Square is a valuable tool that helps children grasp squaring numbers and factoring perfect squares. By building and interacting with the square, children can see, concretely, how a number relates to its square. This hands-on experience is essential for building a strong foundation in both algebra and geometry.

This set includes:

  • instructions for 6 presentations
  • colored squares and rectangles required to build the decanomial square
  • a miniature colored decanomial square
  • a miniature blackline master
