Pattern blocks
From Wikipedia, the free encyclopedia
Pattern blocks are a type of mathematical manipulatives, developed in the sixties by the Elementary Science Studies[1]. They allow children to see how shapes can be decomposed into other shapes and introduces them to tilings. The standard pattern blocks are divided into two different sets. In the first set, the shapes can all be built out of the green equilateral triangle. This set contains:
- Equilateral triangle (Green)
- Regular rhombus (Blue)
- Trapezoid (Red)
- Hexagon (Yellow)
The second set contains shapes that can't be built of the green triangle, but can still be used in tiling patterns
- Square (Orange)
- Small rhombus (Beige)
Pattern blocks form the basis of a number of mathematical activities in schools.
