Lesson objective: Apply knowledge of the defining attributes of shapes to describe and identify shapes.  

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 hide a picture of Atty the Dog under a shape card then describe the defining attributes of the shape to a partner.  The partner will use the attribute clues to identify the shape that Atty is hiding under.  

Key Concept students will use: 

  • Shapes have names that are based on their attributes, and three of these shapes are squares, circles, and triangles.

Skills students will use:

  • spatial reasoning to informally describe the shapes of objects and the relative position of objects (Grade K, Unit 3) 
  • ability to identify and name other two-dimensional and three-dimensional shapes (rectangle, hexagon, sphere, cone, cube, and cylinder) based on defining attributes. 

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they look closely at the structure of shapes on the shape card images to describe and identify shapes.

Key vocabulary: 

  • attributes
  • describe
  • identify

Special materials needed:

  • Where's Atty? game cards (one set per pair of students)
