Determining Area with Square Units
Third graders measure area by counting unit squares inside a rectangle.
Common Core Sheets
Determining Area with Partial Blocks
A more challenging set of worksheets, third graders are required to measure area by counting whole and partial unit squares. Students will realize that two partial blocks make up one whole block. Each shaded figure is on a square unit grid.
Common Core Sheets
Determining Area with Full Blocks
Third graders simply count the square units that make up each figure in order to find the area. Remind the class to count carefully in order to find the correct answer.
