Unit Overview |
|---|
Content Focus –Students work adding numbers within 20, and use their growing understanding of these combinations to refine strategies to solve addition and subtraction problems. They will use a variety of manipulatives, models, and tools to show their strategies and solutions. |
Looking Back…The previous two number units focused on counting, composing and decomposing numbers, and adding and subtracting small amounts. |
Looking Forward…It is important that students work to develop fluency to combinations that make 10. Later in 1st grade, they will apply that understanding to work with larger number combinations. This is a crucial developmental stage in their understanding of the structure of the base-10 number system which they will use for years to come. |
