Well, this led me to convert this creative idea from the Frugal Family Fun Blog into an activity that fit in with our Grocery Store theme and the fruit and veggies walk yesterday.
Water and containers, either individual or shared
I cut out fruits and veggie shapes from the foam sheets. Then each child got a marker, fruit or veggie cut out, a sponge, and a small bowl of water. I showed them how to make the vegetables "dirty" with the markers, and then wash them off with the sponges and bowls.
Wow! That was totally worth the time to cut out the shapes, and the obsolete markers, which will now be used for other activities (because I know there's still some usable color inside those things!)
Now go eat your veggies!
