Unit 2 is typically an eight-week unit taught from November to January.
Children enter kindergarten with a beginning understanding of quantity and the need for counting. Counting with understanding involves more than reciting a sequence of number names in the correct order. In prekindergarten, children counted 10 items using one-to-one correspondence. Kindergarten students continue to use one-to-one correspondence when they count larger groups of items. They apply strategies that help them keep track of items to be counted and further develop their understanding of cardinality beyond 5 items. Many important conceptual ideas about number begin to emerge in kindergarten.
Prekindergarten students identified sets of objects with more, less, and equal numbers by matching. In kindergarten, they create and compare these sets. Their understanding of equal groups provides a benchmark for them to use when making comparisons of more or less. Children also compare quantities when they explore the concept of odd and even, using concrete objects and one-to-one matching.
In Unit 2B, students represent numbers in different ways. Representing numbers with objects brings meaning to children’s use of written symbols, which helps them to be more flexible in their thinking about a number. This number sense strengthens their ability to reason with numbers in complex ways. They connect the spoken number names to concrete and pictorial representations and to written symbols.
The ordinal positions of first and second were explored by prekindergarten students, and these understandings continue to be developed through the fifth position in kindergarten. Understanding how to use ordinal numbers helps children when they describe positions in a sequence of people, concrete objects, or pictures
