Lesson objective: Relate identifying 3D shapes to real-life situations.

This lesson provides an opportunity for students to apply their knowledge and understanding of classifying 3D shapes to a real-life situation. Students are asked to help Sam figure out what 3D shapes, and how many of each shape, she used to build her castle. 

Key Concept students will use: 

  • Shapes can be analyzed and compared by their number of sides and "corners" (vertices) and other measurable attributes. 

Skills students will use:

  • Ability to count, sort, and categorize objects. (Grade K, Unit 3; K.MD.B.3)
  • Two- and three-dimensional shapes can be identified and described as flat or solid. (Grade K, Unit 11)

Students engage in Mathematical Practice 3 and 7: Students look for similarities and differences between each 3D shape. They will explore each 3D shape and present their argument and respond to arguments of others as they figure out how many of each 3D shape is used to build the castle. 

Key vocabulary: 

  • attribute
  • cone
  • cube
  • cylinder
  • prism

Special materials needed:

  • 3D shapes and/or blocks.
