Great way to learn about and review the rock cycle. 18 domino tiles to match with key rock cycle vocabulary. A student worksheet is included. The game may be played without this worksheet as a sponge activity or with it to provide the students a means to record the information they have learned for a study guide. Students may work individually to compete with themselves to improve the time needed to complete their domino line or work in pairs or groups. There's even a pouch for storage.
