How should I write this on my resume?

I'm interning with the HR department for a school district this summer. They also send me to work at summer school for half of the day, which is a completely different set of responsibilities, but it's still part of my internship. On my resume, would I be able to have them as two separate categories, or should I just keep summer school as a responsibility of my internship?

I just have so much to say for summer school that I feel it makes sense to have it be separate, but I don't know if that's misleading, which I'm not trying to be.
