Teachers – are you looking for a great center activity for your kids? How about a sponge activity? Well, this basic skills game will have kids solving problems to reveal pictures, having fun without realizing they are learning at the same time! Students will answer an addition, subtraction, multiplication or division math problem correctly to reveal a piece of the hidden picture. If they happen to work the problem incorrectly, don't worry – the answer will turn red and they can try again. Students can work alone or in groups. Estimated time for the activity is 10-15 minutes.
