I happened upon a box of unused tiles which led me to make this cool project with the kids. They arranged the tiles however they wanted onto a piece of cardboard and then I glued them down with adhesive so the tiles wouldn't slide around. They painted the tiles and then pressed down a piece of paper (we used scrap paper) to make a reversible print. The kids were so excited to see what print they made, over and over again. I can't take credit for this idea, though, I heard about from the incredible Lisa Murphy. So, if you have any old tiles laying around, here is a great way to use them up. Your kids will love it!
