Lesson objective: Solve area problems in which the figure is rectilinear.

This lesson provides an opportunity for students to apply their knowledge and understanding of area of a rectilinear figure to a real-life situation. Students are asked to draw a design for a rectilinear park.

Key Concept students will use:

Skills students will use:

- area
- decomposing rectangles
- multiplication

Students engage in Mathematical Practice 8 (Look for and express regularity in repeated reasoning) as they use the area model to create a rectilinear figure.

**Key vocabulary: **

- area
- area model
- factors
- multiplication
