Skills:

  • Work in pairs to practice the language of math by identifying attributes of 2 dimensional shapes and  key geometry vocabulary
  • Practice taking notes for math learning in order to understand defining and non-defining attributes
  • Distinguish between defining (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size)
  • Create a t-chart and sort/draw objects by attribute.

Materials Needed: Required:

  • Copy of Lilly's Purple Plastic Purse by Kevin Henkes (or similar engaging story)

Lesson Plan Description

Geometry is fun to learn and pairing the math learning with a great book even better!  Our brains are proven pattern seekers so the more we purposefully build connections as we teach, the better students will learn, apply and transfer the skills.  In this lesson your “littles” will:

  • Work in pairs to practice the language of math by identifying attributes of 2 dimensional shapes and  key geometry vocabulary
  • Practice taking notes for math learning in order to understand defining and non-defining attributes
  • Distinguish between defining (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size)
  • Create a t-chart and sort/draw objects by attribute.
