Grimm's Colorful Bead Stair
An exciting way for children to discover the world of numbers!
Each number can be counted by feeling with the hands. The eyes can see the difference when the strings are laid out. Together with the number sets, the counting blocks, the counting figures, the Counting Stack game and the 5 Math Friends there is a super way to learn through Grimm's rainbow numbers.
