Teacher's Demonstration Rekenrek

Great teaching tool ! Large counting frame features 100 plastic beads in red and white on 10 rails. (color change after each 5 beads) the upper 5 bards have 5 red beads on the left and the lowest 5 bards have white beads on the left . This reinforces that 100 is composed of two sets of 50. Useful to demonstrate addition and subtraction up to 100.
