This 100-bead rekenrek counting frame helps young children build number sense and develop strategies for counting to 100 using anchors of 5 and 10, as well as adding and subtracting, and subitising. It’s ideal for when students progress from using our 20-bead rekenreks (sold separately) to working with numbers up to 100. The sturdy wooden frame stands upright, which allows students to easily move the red and white beads across the rows when learning at their desks.
