Play a game with your students where they actually get to throw something at the SmartBoard - totally safe for your SmartBoard if you use a Koosh Ball. You know one of those soft balls with all the crazy looking "hair" sticking off of it! Our ITRT shared the idea and the kids love it!
Practice everything decimals with this game - place value, value of the digit, comparing, ordering, rounding...
You will download a totally interactive SmartBoard! Drag the infinite cloner and cover up each square as you complete that number. That way when the kids throw the ball again they won't get the same question!
