Number bonds and rekenreks are both powerful tools, but use them together and watch out. Students will be able to make connections between the two models and be able to see the math and the problem and decompose it and think flexibly with numbers to solve the problem. Your students and your parents will LOVE this! Included in this set are cards for each problem that can be represented on a 100 Rekenrek. Thank you for visiting more store and I hope you check out the rest of my amazing products.
