This file includes 20 cards with 1-20 minions on each card. Children count the minions and use a clothespin to clip the correct number. Perfect for a counting center. To make this a self checking center activity make a dot or place a sticker on the backside of the correct answer. The clothespin should cover the dot or sticker when it is clipped to the correct number. Children can then turn it over to check if they counted the correct number.
