K-2 Addition and Subtraction Strategies contains over 100 worksheets to develop number sense and computational fluency. All content is aligned with the Common Core State Standards and provides opportunities for paper and pencil practice to develop a framework of mental strategies on which more advanced thinking techniques can be built. Intended for use after students have explored these mental strategies using concrete materials, this resource is ideal for small group instruction, homework or assessment purposes.
Section 1 focuses on developing efficient strategies for learning and internalizing the basic addition (0+0 - 9+9) and subtraction facts. Addition strategies include counting on, doubles, facts of five, near doubles, and facts of ten. Subtraction strategies include counting up, counting back, and thinking addition.
Section 2 focuses on more advanced addition and subtraction strategies based on place value, properties of operations, and the relationship between addition and subtraction. These strategies take students beyond the basic facts and allow them to see how previously learned mental strategies can be used to compute problems with larger numbers.
