Teaching Notes

Introduce perimeter as the distance around a shape. Students can count units on a grid or add side lengths for given shapes.

Vocabulary
Perimeter: The total distance around the outside of a shape.
Compare: To look at two things and see how they are alike or different.
Common Mistakes
  • Counting corners or vertices instead of units along the edges.
  • Miscounting units, especially with irregular shapes.
  • Incorrectly comparing the final perimeter values.
Differentiation
SupportProvide grid paper; highlight the path around shapes.
ChallengeUse shapes with varying side lengths; include non-grid examples.
Discussion Questions
  • What does 'perimeter' mean in your own words?
  • How do you find the perimeter of a shape?
  • Why might we want to compare the perimeters of different shapes?
  • Can two shapes with different appearances have the same perimeter?
Extension Activities
  • Draw shapes with equal perimeters.
  • Find shapes with the largest perimeter.
  • Create a perimeter comparison chart.
Parent Tip

Have your child measure and compare the perimeters of different rooms.
