Base Ten Blocks - Addition and Subtraction

This math unit begins by teaching students to understand and perform addition using visual aids, specifically through the use of base 10 blocks. It initially covers simple addition without carryovers in smaller place values and progresses to handling larger numbers and carryovers in higher place values. The unit then introduces subtraction, following a similar progression. Students learn to perform subtraction using visual cues by translating images into equations, both with and without the necessity to borrow. Throughout the unit, learners develop the ability to visualize and solve arithmetic problems in both addition and subtraction, starting from tens and ones and advancing to thousands and hundreds. Students enhance their skills in interpreting visual data to solve equations, increasing their comprehension of place value and the mechanics of carrying and borrowing within the base 10 system.
