Practice finding the perimeter of regular and irregular polygons using a geoboard. It only takes a few moments to print these pages that make differentiation a snap.

This measurement resource includes:

• 15 different pages that practice calculating the perimeter of regular and irregular shapes with geoboards. Students do not need access to a geoboard to complete these activities, but being familiar with how they work is beneficial.
• all 15 pages have answer keys.
• Canadian/British spellings and metric measurements (cm, m km).
• SI Notation, so numbers are written with spaces between place values instead of commas. (Example: 2 000 instead of 2,000).

Ninja Note: This resource was not designed with Easel by TpT in mind. It works best when printed.
