Skills
- identify (two-dimensional shapes: circles, triangles, rectangles, squares, rhombuses, hexagons) #dok1
- describe (attributes of two-dimensional shapes using formal geometric language) #dok2
- distinguish (shapes based on their attributes) #dok2
Learning Targets
- I can identify circles, triangles, rectangles, squares, rhombuses, and hexagons. #dok1
- I can list or point out important attributes of two-dimensional shapes. #dok1
- I can describe two-dimensional shapes using correct geometric vocabulary (such as sides and vertices). #dok2
- I can compare two-dimensional shapes based on their attributes. #dok2
- I can explain how certain shapes are special types of rectangles (like squares). #dok2
Big Ideas
- Two-dimensional shapes have unique and shared attributes that can be identified and described using geometric language.
- Understanding and communicating about shape attributes helps us compare, sort, and classify shapes in the world around us.
Essential Questions
- How can we recognize and name different two-dimensional shapes?
- What words can we use to describe the attributes of shapes?
- How are some shapes special kinds of other shapes (like a square being a special rectangle)?
- Why is it important to use correct vocabulary when describing shapes?
- How can you compare the attributes of two different shapes?
