Find the area of a shape by counting unit squares
Describe the relationship between area and perimeter
Build shapes with a given area and/or perimeter
Find the area of an irregular shape by decomposing into smaller, regular shapes (e.g., rectangles, triangles, squares)
Determine the scale factor of similar shapes
Generalize how area and perimeter change when scaling shapes

This resource provides ideas for a family math night focused on area and perimeter for Grade 3. This could also be adapted for Grade 4. This is remixable.

Students brainstorm and discuss the different types of materials used to build houses in various climates. They build small models of houses and test them in different climates.

This 3 unit of measurement lessons explores area through 2 hands-on activities and 1 worksheet.

In this lesson students calculate the areas of polygonal figures. They use hash marks to create square units and to count the units, including half-units.

This short video and interactive assessment activity is designed to teach second graders about multiplying lengths (english units).

This resource is from Tools 4 NC Teachers. This document is the About the Cluster document for Cluster 6 created by the authors of the NC2ML Instructional Frameworks. This document should be read prior to teaching Cluster 6. This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.

For this lesson, students use tiles and grid paper to draw rectangles and record the perimeter and area of each rectangle.

This resource contains a link to an interactive whiteboard activity and other various resources for determining perimeter and area.

In this lesson students find the area of a rectangle by tiling it with unit squares. 

Students pretend they have been hired to design five enclosures for the animals at a local zoo. Students use their knowledge of area to calculate area and perimeter in order to design the proper enclosures and earn ZooDesigners points. Once the interactive opens, click on "create exhibit" to begin.
