These challenge capsule inserts will serve as a sponge center or motivational tool to get students to finish centers, and still want to work more. Just purchase capsules online from Amazon or another company and place these inserts along with a prize inside. The kids need to do the task listed on the card, then they keep the toys/candies. It's that simple. The tasks I have on this file range from authors purpose, to grammar and phonograms. This will help you get started with challenge capsules.
