Creating Pattern Block Shapes and Measuring Perimeter

posted Oct 25, 2018, 6:03 PM by Patrick Johnson
Students have been learning to measure perimeter. In this task, students used 6 pattern blocks to make a shape. Then they measured the perimeter (1 unit equals 1 side of a triangle).

Afterwards we sorted the shapes by the size of their perimeters. During our math consolidation, one student observed that the shapes with the smaller perimeter have more sides inside (interior of the shape) therefore those sides are not counted as part of the perimeter. The shapes with the larger perimeters are longer and more sides are counted.
