We do a lot with easter eggs and use it for looking at colours ad textures. Love to put rubbing plates or anything with a texture under the paper for them to rub a crayon over. Change colour of crayon frequently to make the eggs extra pretty. Change paper and plates and let them make more. They love to take home 2-3 eggs per day and it uses a large block of time because we talk about each person's egg and I make some too so I get the patterns really deep. We call them surprise eggs since you don't know what you will get till you start to colour. If you don't have rubbing plates something that works well is a piece of plastic canvas which you can buy at the craft store. Then it makes a little square design. Shift the paper on the canvas - tape it in place with each colour change and the square design will turn as well.
