Addition and Subtraction Strategies

Description

This learning resource focuses on fundamental addition and subtraction strategies. It begins with the 'Part-Part-Whole' concept, using number bonds to illustrate how two parts combine to form a whole. Various addition strategies such as 'Counting On,' 'Making Tens,' and 'Doubles +/- 1' are introduced, along with hands-on learning using Base-Ten Blocks for visual and tactile reinforcement. The document transitions into subtraction, defining it as 'taking away' and providing strategies like 'Counting Back' to visualize operations on a number line. Readers learn to use related addition facts to assist with subtraction, followed by practical examples and word problems that challenge students to determine whether to add or subtract. It also includes a section on 'Fact Families' to reinforce the relationship between addition and subtraction, and wraps up with mixed practice problems designed for real-world application.
