In this unit, students will use their knowledge of shape attributes to model and compose shapes. Students will build 2D and 3D shapes based on given defining attributes using a variety of models and materials, (e.g., toothpicks or clay). Students will also begin to understand that shapes can be composed by combining smaller shapes.
Key Concepts:
 We can model shapes in the environment by building them from components (toothpicks, clay, etc.)
 We can draw shapes to model shapes in the environment.
 You can compose simple shapes to form larger shapes (two triangles can be joined full side to full side to form a rectangle.)
Prior Knowledge Needed:
 Model and build shapes; (Grade K, Unit 5; K.G.B.5)
 Analyze and compare shapes by their number of sides and angles; (Grade K, Unit 11; K.G.B.4)
Units on the Horizon:
 Composing and Drawing Shapes (Grade 1, Unit 12)
 Reasoning with shapes and their attributes (Grade 2, Unit 10)
