Lesson objective: Understand that the last number name said when counting the objects in a collection names the quantity of objects in that collection.

Students bring prior knowledge of counting from K.CC.B.4a. This prior knowledge is extended to understanding that the last number counted names the number of objects in a set as students practice counting sets of objects and telling how many. A conceptual challenge students may encounter is understanding that the last number said represents the quantity of objects counted, not only the object counted using that number. 

The concept is developed through work with blocks and visuals of pets, which help students practice counting with concrete and familiar items.

This work helps students deepen their understanding of number because they are building the concept of cardinality.

Students engage in Mathematical Practice 6 (Attend to precision.) as they count each item carefully.
