I agree with a lot of what Angelynn wrote. You have such a huge range. If it was me, I'd maybe divide the class into 3 groups: low, medium and high. I would plan 3 lessons for every class. I know this sounds complex, but I've done it and it can be done. I spent each class period walking around to the different groups and helping them as necessary. In planning, I tried to use activities that would take 45 to 90 minutes each. That way my lessons were not too complicated to plan and not too exhausting to carry out in class. I like to give the high students their activity first, since they may bore easily. Then once they have started, I move to the middle group and give them instructions for their activity.
