Description
Help your 2nd graders practice two-digit subtraction with regrouping using number lines! In this 16-card Boom™ Cards deck, students follow backward jumps on a number line to solve subtraction problems within 100. They subtract tens first, then break apart the remaining ones to jump back to a friendly ten before reaching the final answer. Students use the visual number lines to follow each step and type the difference. This activity helps students strengthen their understanding of place value, develop mental subtraction strategies, and build confidence with regrouping. Perfect for Grade 2 math centers, independent practice, small-group instruction, or subtraction strategy review.
