Just need a different idea than the balloon. Wacky sacks are balloons filled with playdough. Keeps kids' hands busy while they focus on the teacher :). Can serve as a stress ball for teachers too! All directions are here along with pics.
paint a flowerpot and saucer with glossy white paint. Use a foam brush to paint the rims with a coordinating color. Fill with potting soil and a packet of seeds. turn saucer over top of the pot. tie with a ribbon and tuck a trowel in the bow
