1. RECYCLE. We have 2 different trash cans so the kids can separate trash vs. recycling. Added bonus: They know the difference between plastic, glass, and aluminum foil.
2. REUSE. I have them place gently used plastic baggies on the counter to use again. I also have them go through their old toys to give to charity (some forgotten toys become another’s treasure). Last, I get books at the library for the whole family. The kids love the variety. Added bonus: Most libraries offer free e-book on their websites.
3. REDUCE. I know it’s hard enough to get them to wash their hands, but I found my kids were wasting so much soap and water (we wash hands A LOT!). We changed the routine so they can use only one pump of soap and lather up before they turn on the water. Add bonus: they get much more bubbles doing it this way.
