Learning to count is cool, isn't it? Especially when we use this pretty slide rule from Janod with its 5 rows of 10 colorful wooden beads. The little ones first learn the colors (10 in total) and practice their fine motor skills by moving the beads. Older children learn to count and can even perform their first simple operations such as adding and subtracting. Complete toy whose activity develops with the child. Toy made from FSCTM-certified wood. Motor skills toy for children aged 18 months and over.
