What can I do about this math dilemma? My daughter lost her tutor?

My daughter is in grade 5 (homeschooled). I've been teaching her math since grade 2 (she went to school before then), which was fine. However, now that she's older, I find that teaching her math is getting too difficult and I, myself, don't know the concepts or remember them from school! We're getting into improper fractions and I wouldn't know how to teach her. She had a tutor in the fall (he was a friend of ours and was teaching her for free) but he's no longer available. I can't afford a tutor either. What can I do? I don't want to send her into a clroom either to learn math. Any suggestions? I feel at a loss right now.
