Here is an OOH campaign for the COA Youth & Family Centers in Milwaukee to raise awareness of the positive impact parents' involvement with their child's education has with success in the classroom. They have done it in a very cool interactive way to show it is HIP to "Get Involved Your Child's Education":
These "guerrilla" classrooms have interactive learning displays where parents could see "how many centimeters tall you are," or "solve this puzzle," or "read a story," or "learn about angles" or "find out how much you weigh on the moon" with their child.
The campaign included a bus wrap that looked like a safari jeep stressing that parents could "learn about nature" with their child.
