Unit 7, Lesson 7
Put Together Flat Shapes
Grade 1
Preparation
Lesson Narrative
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.
This lesson has a Student Section Summary.
- Action and Expression
- MLR8
- Create two-dimensional shapes and figures composed of smaller two-dimensional shapes.
- Describe (orally and using words or other representations) two-dimensional shapes and figures composed of two-dimensional shapes.
- Let’s build a new shape from smaller shapes.
Required Preparation
- Create a chart, titled “What We’ve Learned about Shapes,” for the Lesson Synthesis.
- Consider making the blackline master into a packet for each student.
- Each group of 2 students needs at least one picture book that shows a variety of shapes.
Suggested Centers
NoneTeacher 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?
