Today I rolled out a large sheet of white paper and at each end put a baking tray with some paint in. The girls soon found it and started walking up and down on it with much giggling! They really enjoyed the experience of the paint. This was good for messy play, colour mixing and numeracy (how has the biggest feet, who can make the biggest gap between prints - this could extend to measuring). The only thing is it can get quite slippery so we painted on the grass where it didn't matter about the mess or falling over!
