Lesson objective: Count to answer "How many?" and then build a collection to match.

This lesson helps to build fluency with counting to tell how many. Cubes are used here because they support students as they model a collection they have counted. 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 count a set of objects and then build a set to match. Students apply various counting strategies to make sure they have counted accurately.
