Grade: 4

 

Sample Activities:

 

·        Students use square, triangular, and hexagonal grid paper to create colorful designs. They discuss why these polygon shapes fit together like a puzzle.

 

·        Students use Unifix cubes or pattern blocks to create designs. They then discuss how many blocks they used (area) and the distance around their design (perimeter).

 

·        Students work through the Tiling a Floor lesson that is described in the First Four Standards of this Framework. They discover that the shapes which can be used for tiling must be able to fit around a point without leaving spaces and without overlapping.
