Mess Free Finger Painting for kids! thanks from maria frazer. Paint into Large Ziploc bags with a piece of paper in it. Then tape the whole thing down and let the kids play. No mess, because the whole thing is contained in a ziploc!
Cardboard boxes makes shape jumping even cheaper to do! You call out the shape & color & the child's job is to find the shape & matching color. Fun, active activity for large motor development & body & eye coordination.
