Learning Objective
I can measure perimeter around shapes.
Today we will learn how to measure perimeter around shapes. Math helps us solve problems and understand the world around us.
Geometry is the study of shapes, sizes, and the properties of space. Basic shapes include circles, triangles, squares, and rectangles. We learn about angles (corners where two lines meet), lines (straight paths that go on forever), and points (exact locations). Understanding geometry helps us describe the world around us and solve problems about distance, area, and volume.
Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!
Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.

A question we need to solve
Instructions
Materials Needed
- Counters or objects
- Pencil
- Practice sheet
A rectangle has length 8 cm and width 5 cm. What is its perimeter?
A square has sides of 4 inches. What is its perimeter?
Find the perimeter: Triangle with sides 3 ft, 4 ft, 5 ft.
Teaching Tip
For younger learners: Use concrete objects and hands-on activities when teaching measure perimeter around shapes. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
