My daughter sat at the kitchen table coloring her trees pink and her grass red and her mermaid (lying on the grass, naturally) a whole rainbow of crayola. As I prepared to settle my youngest child for his nap, the two oldest needed an activity to keep them busy for a bit. I grabbed my daughter's crayons, drew some colored dots on scrap paper and placed the labels into an empty egg carton. Then, I sent my 7-year-old daughter and her five-year-old brother outside, carrying the egg cartons which were to become paintboxes from nature. Multiple versions were made and filled with ripe fruits, tiny blossoms, flecks of dirt... and I got the youngest his nap without interruption. Brilliant. Side note: a five year old doesn't mind adding a live snail to his 'paint box' but will move the silver and brown label side by side so that the color label will be right even if the snail decides to move.
