Homeschool World Forum

I know I saw this subject on the forum but I can't find it now. How do you homeschool for a 2nd grade, 5th grade, and 7th grade at the same time. Also, is there a way to do Biology labs with my 7th grader without spending a lot of money on lab equipment?

Two ideas come to mind.
1. Chose something that everyone can study together, like a unit study. Konos and WinterPromise could give you ideas.
2. Chose a program that encourages independent learning-like Alpha Omega.
Hope that helps!
