3rd Grade Math - Perimeter

Updated: Jan 20

This post explains and gives practice opportunities related to TEKS 3.7B:

determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems


Perimeter is more than just adding up all the sides. Sometimes students are given a perimeter and need to use that to find missing sides.
