Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Encourage students to explain the relationship between decimals and fractions to help them with future computations. Use this lesson on its own or as support to the lesson Area with Decimals and Fractions.

Area models are building blocks to more complicated multiplication and division. Use this lesson to refresh students on the relationship between multiplication and area to prepare them to use the area models strategy with larger numbers.

Start a dialogue around area models! In this lesson, encourage students to ask questions as they multiply using area models. Use this lesson on its own or as support to the lesson Area Models and Multiplication.

This lesson helps your students become confident mathematicians when it comes to representing fractions visually in a variety of ways. Use this lesson as a pre-lesson to Fraction Hunt or teach it independently.
