Black And White Bead Stairs: Individual Beads Nylon: 1 Set

The Black and White Bead Stairs are the counting aid the snake game leans on: bars of one to nine beads that hold the remainder once a group of ten has been exchanged. Because their colours differ from the coloured bead stair, the child sees at a glance which bars belong to the result and which are still being counted. One set with individual nylon beads. For children from three years working on addition and subtraction with the snake game.
