Using number lines to teach addition and subtraction has always been in my tool box. This product includes a variety of number line addition problems that can challenge students in grades 1 - 3. I've used this product to differentiate instruction for students. Students need to show how they added the numbers together by placing the operations above each number line. Please see the free sample if you have any questions. An answer sheet with sample answers is provided.
