How Many Circuit Playgrounds

Looking to teach Unit 6 for the first time. Haven’t looked in depth yet but getting ready to acquire the circuit playgrounds.

I have 3 sections…23, 23, and 28.

Is one set of 15 enough or would it be a mess to have students sharing across sections?

HI, I have had multiple classes use my class set.

Pro tip: keep you cables connected the Circuit Playgounds and the connections last longer. I saw one teacher hang them on Command hooks in her room using the cable and just always left them attached to the Circuit Playgrounds. I thought that was an interesting idea. It keeps kids from plugging and unplugging them across multiple classes. She uses one set of 15 for four 6th grade classes.
