First, we did school on the deck... moments before the umbrella got sucked up by the wind and blew into the yard!
Followed by an unplanned lesson in Economics at a local Homeschool Flea Market, where local moms sold curriculum, clothes, toys, etc. - and where my kids decided to sell homemade rubberband bracelets (Lily) and random household junk (Jacob).
Watching their innate selling tactics in action was eye-opening for me. Lily came prepared with homemade signs, her wallet, and a firm selling price. Jacob came prepared to make as much as possible by going table to table, asking anyone would listen if they would pay, say, $10 for an old pen, or $2 for his (nearly-broken) dollar store toy. The boy had NO FEAR.
Next time we buy a car, we're totally taking him with us.
In the end, he spent all the money he made on snacks other kids were selling, and Lily - who only sold one bracelet (there was fierce competition) and gave another one away - spent her money on one snack and a cool magnetic pattern game.
Then they played on the adjoining playground for a long, long time - it's so hard to leave when they're making homeschool friends we can actually meet up with during the week! - and I almost passed out (I exaggerate not) from dehydration by the time we finally left. Lesson learned: always bring water, even when you're only planning to be out for an hour, because on a beautiful day, when the kids are being wonderful, it could easily turn into four.
