K-2 Addition and Subtraction Strategies contains over 100 pages of pencil and paper practice to develop skills and concepts critical to the development of number sense and computational fluency. Ideal for small group instruction, homework or assessment purposes the materials in this resource provide a framework of mental math strategies on which more advanced thinking techniques can be built.
Section 1 focuses on developing efficient mental
strategies for learning and internalizing the basic addition and
subtraction facts. Section 2 focuses on more advanced
strategies for addition and subtraction based on place value, properties
of operations, and the relationship between addition and subtraction.
