Lesson objective: Apply understandings of special shape attributes to build shapes with materials.

This lesson provides an opportunity for students to apply their knowledge and understanding of defining attributes to a real-life situation. Students are asked to create a map of a shape playground by building shapes with straws and clay to represent specific playground equipment.

Key Concept students will use:

- We can use various components to model shapes in the real world.

Skills students will use:

- ability to name shapes based on their defining attributes.
- ability to identifying shapes based on defining attributes, regardless of their size or orientation.
- ability to use position words to describe object location (Grade K, Unit 3).

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they use what they know about the defining attributes of shapes to build shapes to represent playground equipment.
