Listen and Repeat

While straightening up the classroom today I noticed scuff marks on the floor. All was not lost I grabbed some of our handy dandy magic erasers and got to work. One of my boys asks "Oh oh can I help?" I toss him a sponge and reply "Sure knock yourself out." I continue cleaning but he gets bored and goes back to playing. After a while he returns and asks "Can I do it again?" Before I can reply he grabs a sponge and and says, "Knock yourself out."
