In previous lessons, students used geometric understanding to solve problems involving the design of wax prints and parks. In this lesson, students create a robot as they draw parts with specified perimeters. Students then find the area of robot’s body parts they drew and consider different areas that can be drawn with the same perimeter. If time allows, students can color their robots to highlight their mathematical ideas. When students recognize mathematical features of objects in the real world, they model with mathematics (MP4).
- Apply geometric understanding to solve problems about robots.
- Let’s use perimeter and area to design robots.
Materials to Gather
Materials to Copy
- Square Dot Paper Standard
- Students will need to tape together at least 2 sheets of the square dot paper to have space for their robot.
Teacher Reflection Questions
As you finish up this unit, reflect on the norms and activities that have supported each student in learning math. How have you seen yourself grow as a teacher? What are the things you most want to work on as you head into the final unit of the year?
- Can You Draw It? (1–5), Stage 4: Area and Perimeter (Addressing)
- Compare (1–5), Stage 4: Divide within 100 (Supporting)
- How Close? (1–5), Stage 5: Multiply to 100 (Supporting)
