Nuts, Bolts, and Pattern Cards Class Set

2 years & up. Encourage color and shape recognition while building fine motor skills. In this class set, children connect bolts to cards by matching a bolt's shape and color with the corresponding shape and color on the card. Children then fasten the bolt to the card with the nut. As children get the hang of it, they can continue to challenge themselves because the set comes with cards that have higher levels of difficulty. Bolts measure 2.75".
