Put your kids to work doing some tasks that are a big help to Mom and Dad, but that they enjoy too.
Organizing plastic containers. Sort the plastic containers: bottoms in one pile, tops in another pile. Then, match up each bottom container with the appropriate top.
Any top without a bottom, or bottom without a top can be recycled. (Where did those missing pieces go?) Also, consider donating or recycling any excess if you find that you have too many of one size. If you end up with one extra larger-sized bottom, it could be used to hold the tops. Stack smaller containers inside larger ones.
Replace the containers to your kitchen cabinet.
