# Perimeter Robots

Description

Get your students applying their perimeter knowledge in a creative way! Students create a two-dimensional robot on the grid paper provided and using the 1cm grid paper, calculate and record the perimeter of each body part. Students can then decorate their robot. This is a great class display and tool to assess students understanding of measuring perimeter.
