Curriculum for a new homeschooled 7th grader and Summer "warm up" ideas?

Hey everyone. I rely heavily on your comments, ideas, concerns and feedback. I am a mother to a current 6th grader who is in public school. She has voiced desire for homeschooling for about 1 year now and I am seriously considering it. She will begin homeschooling for next school year. Does anyone have a 7th grade curriculum layout that there are currently using, will use or has used in the past? Please share. Also, since I am completely new to this culture, does anyone have any ideas for a summer “warm-up” to get our feet wet?

Thank you SOOOO much!
