In previous lessons, students made composite shapes from three-dimensional shapes.
The purpose of this lesson is for students to compose shapes from smaller, two-dimensional shapes. They observe how the different pattern block shapes fit together to make larger shapes and how there are different ways to compose the pattern blocks to make the same shape (MP7). In the lesson synthesis, students reflect on what they have learned during their study of shapes in this section.
- Action and Expression
- Compose shapes in different ways.
- Construyamos una nueva figura usando figuras más pequeñas.
- Create a chart titled, “What We’ve Learned About Shapes” for the Lesson Synthesis.
- Consider making the Flat Shapes Puzzles blackline master into a packet for each student.
- Each group of 2 needs at least one picture book that shows a variety of shapes throughout the book.
Teacher Reflection Questions
Reflect on how you can reinforce the work done in this section outside of math class. When can you ask students to identify, describe, or compose shapes?
