[Gr. 10] Any online "workbooks" or other resources for Pre-Calc 10?

I'm going away on holiday for a month, and I'd like to prepare for next year. I'm going into Gr. 10, and I need something which would work for Foundations of Math. and Pre-Calculus. It doesn't need to match my school's curriculum exactly, I was just wondering if you guys knew of any online resources I could look at.

Thank you so much!
