This Christmas themed game is great for math centers, tactile learners, or early finishers. Have students find the missing numbers from 1-50. The numbers are in numerical order so the games can be broken down into learning 1-25 and 25-50. Add velcro or magnets for extra fun! I've used these laminated in file folders and in sheet protectors in a binder. They can be done individually or in a small group.
