Lesson 10
Solve Area Problems
Lesson Purpose
The purpose of this lesson is for students to solve problems involving area.
Lesson Narrative
In previous lessons, students found the area of rectangles with tiles, grids, partial grids, or linear measurements marked along the sides of the rectangle. Students also used rulers to find the area of rectangles.
The problems in this lesson are about a community garden. Consider launching the lesson with a read-aloud of City Green by DyAnne DiSalvo-Ryan to get students thinking about different aspects of a community garden. Students might draw squares within rectangles, draw tick marks on side lengths, count groups, or multiply to find area in this lesson. Any reasoning that makes sense to them is acceptable.
