Division Problem Slips in two boxes give lower elementary children the independent practice material they need to consolidate long division work introduced with the stamp game, test tube division, or racks and tubes. Teacher-prepared slips are time-consuming to produce in sufficient quantity, and this set provides the volume needed for children to genuinely internalize the operation through repeated, self-directed application. Two boxes allow you to differentiate within the classroom by offering problems of varying complexity to children at different points in their division progression.
