Students should be able to count a set of objects and determine that the last number they counted represents the quantity of the set. For example, a student counts 1 red bear, 1 blue bear, 1 red bear, 1 green bear, 1 green bear, 1 blue bear, 1 red bear, and 1 green bear in a set and states there are 8 bears. If the bears are rearranged such as 1 red bear, 1 red bear, 1 red bear, 1 blue bear, 1 blue bear, 1 green bear, 1 green bear, and 1 green bear, the student should understand and realize the set still contains 8 bears regardless of how they arranged.
