Addition and Subtraction Stories and Counting to 20
Module 5 is the culmination of children’s work with number in the Pre-K year. Throughout Modules 1 and 3, they had extensive counting experiences with numbers 0–10. In Module 4, they examined the relationships between numbers 1–5 through comparison. In Module 5, children transition from the comparative concept of more (4 apples is more than 1 apple) to the concept of addition (3 apples and 1 more apple make 4 apples). They are ready to begin work with operations, focusing on addition and subtraction stories with numbers 1 to 5. Students will also learn to write numerals 0-5 and explore patterns in this final module.
