Addition and Subtraction of Integers - 1 and 2 Digit

This math unit focuses on developing fundamental arithmetic skills, centering on addition and subtraction with integers using varied methods and representations. It starts with basic subtraction of positive integers using number lines, where learners interpret visual information to solidify their understanding of numerical operations. The unit progresses to addition, including identifying missing values and understanding addition sentences using visual aids like number lines and base 10 blocks. The complexity gradually increases from simple single-digit calculations to more intricate two-digit operations involving borrowing and carrying. As the unit advances, it introduces subtraction and addition using base 10 blocks, enhancing the ability to visualize and calculate differences and sums, particularly emphasizing borrowing and carrying over across hundreds, tens, and ones. This culminates in exercises that require students to solve problems represented in visual formats and interpret relationships in fact families. By the end, learners are adept at manipulating and understanding both single and double-digit numbers using a variety of tools and strategies, refining their arithmetic proficiency and readiness for more complex mathematical concepts.
