Designed by a Montessori teacher to aid the development of eye-hand coordination and teach a practical skill. This is the most challenging of the three boards we offer because the bolts are graded in diameter.
The five slotted bolts must be sorted by size and then screwed into the long-lasting metal sleeves that prevents stripping. The board has two troughs: one to hold the bolts after the child has removed them and one for the driver. Ages 3+.
