Help her only when she is stumped on solving the problem and about to give up. Using the hobby knife or scissors, follow the tracings to cut holes in the lid. Check to make sure each object fits through its hole. Make sure there are no rough edges around the holes. Cover the bucket with contact paper if you wish.
Place objects into the bucket and close it with the lid.
Show your child how to open and close the lid. Carefully clean all materials and containers by washing and rinsing. Disinfect after washing with a solution of one tablespoon of bleach to one quart of water, then air dry the item. Smooth any sharp edges. Make sure there are no sharp points or splinters on the item.
