This set of four mini wooden rekenreks is the perfect tool to introduce and reinforce number sense to young children. Each row consists of ten beads, split into five red and five white beads. Young learners may use this manipulative as a hands-on introduction to basic counting, while more advanced learners can practice subitizing, addition, subtraction, skip counting, and more. A second row of beads is included to allow learning to expand beyond counting to ten.
