5. Sort shapes (FP)

Lesson objective: Sorting and count to identify how many objects are in a category. 

This lesson helps to build fluency with sorting and counting objects. Shapes are used here because they are familar and can be a concrete representation of a number. This work develops students' understanding that objects can be grouped and counted.

Students engage in Mathematical Practice 3 (Construct viable arguments and critique the reasoning of others). Students will defend their choice in categorizing objects and counting objects.

Key vocabulary:

  • color
  • group
  • shape
  • sort

Special materials needed:

  • number cube
