Lesson objective: Count a collection and tell how many.

This lesson helps to build fluency with counting. Cubes are used here because they support students in flexibly counting with strategies of their own choosing. This work develops students' understanding that the last number name said tells the number of objects counted.

Students engage in Mathematical Practice 6 (Attend to precision) as they build a set of objects to match a given number and then count the set of objects.  Students apply various counting strategies to make sure they have counted accurately.

Key vocabulary:

  • cubes
