Our Addition & Subtraction collection equips classrooms with tools to build fact fluency and strong number sense from early grades onward. Resources include ten-frames, number lines, rekenreks, place-value blocks, and card or game sets that model strategies such as counting on/back, making ten, decomposing numbers, and using fact families. Materials support small-group instruction, centers, intervention, and independent practice—covering single-digit facts through multi-digit computation with and without regrouping.
