If you feel like you’re strapped for supplies, think outside of the box: What about a box where your children are encouraged to make musical instruments out of items from the recycle bin? Or what about a box where children have to make funny poems by cutting out words from an old newspaper or junk mail that accumulated over the last week? Or, what about a simple envelope with a “secret mission” for the day--maybe building a “spy” training obstacle course in the backyard?
