How To Write A Resume For A Teacher Recommendation?

My homeroom teacher would be really honest about me in a recommendation (even though we’re not on lovely terms), because she’s known me and my habits/mannerisms the longest, but I overheard her asking for a resume from my classmate when he asked for a recommendation.
I’m not sure how to format/begin/write a non-job resume. Help?

My Guidance Counselor Asked Me To Fill Out A Resume For Her To Write A Recommendation For Me. Help!?

How legit does it have to be? Do I need a cover letter? What do I write for the objective part or whatever?
Should I use Bridges.com to create the resume ??
