This is a game where students practice adding and decomposing sums up to 12.  The game is for 2 players and requires two six-sided dice, and a 10-Pin Limbo! game sheet.

Students will use unit cubes (or other counters), spinner, dice,  to build understanding of doubles Working with the doubles strategy is imperative for students to understand how to apply other strategies. Included are several tasks and activities that you can use and/or rotate throughg with students as they progress to proficiency using the doubles strategy. As students work with and learn the doubles strategy (especially at the beginning) they should record their results. This can be done using a sums within 20 addition table which can help students to visualize the pattern.
