Two-Digit Addition & Subtraction Adventures

Description

This resource focuses on teaching students multi-step word problems using part-whole strategies for addition and subtraction of two-digit numbers. It begins with an introduction to the part-whole concept, emphasizing the relationship between parts and the whole. Through examples and guided practice, students learn how to visualize numbers using manipulatives like Tens Frames and number lines. The lessons progress to incorporate addition with regrouping, where students practice decomposing numbers, and subtraction strategies, including regrouping in word problems. The resource includes various scenarios for students to solve missing part problems, reinforcing their understanding of how to find unknown quantities. Finally, mixed practice problems help solidify their skills, encouraging them to choose their preferred strategy for solving multi-step problems. Overall, this comprehensive approach supports problem-solving and critical thinking in mathematical contexts.
