Music center for preschool playground. Spray paint pots and pans and hang them along the fence. Let the students explore with different "drum sticks." They could make music with their hands, hard sticks, or soft covered sticks. Let them discover what creates different noises.
Have some fun outdoors this summer by making this super easy and cheap obstacle course using pool noodles from the dollar store and bbq skewers. Great for children who are learning to crawl or for older kids to practice ball skills.
