this looks like a great mothers day/grandparent gift/ teacher gift idea. Lots of options with flowerpots, buckets, etc to put it in and with the types of flowers or stems to use and filling in the pail.
Math Match-up! Have students do the problem located on the clothes pin and match it up with the correct answer on the piece of paper. A creative game to work on multiplication/subtraction/addition, and could easily be used at a math center.
