Although children Age 3+ will enjoy playing with this craft, it's a bit fiddly to make so I've rated it Age 5+.
NOTE: you can't paint styrofoam
with tempra paint or washable markers. It doesn't cover well
and it will flake off when it's dry. Acrylic paint or permanent
markers work well, but most of us don't want our kids using them.
The solution I've come up with is to have the girls assemble the
craft on day 1. In the evening, I paint the craft with white
acrylic paint (you can buy it for less than $1 at Walmart or the
craft store and it will work for many crafts). It dries
overnight and in the morning the girls can paint over it with tempra
paint or color over it with Crayola markers!
Cut three pieces from your egg carton (shown from left to right in the photo):
cut the bottom of the middle two cups off the 6 cup strip.
Glue the two cup strip onto the front of the six cup strip
Optional: prime the truck white acrylic paint.
