Question: 8th grade math for public schools kids in NYC?

So I’m tutoring math for two eight graders in a school in Washington Heights (a volunteer program), which I wouldn’t call inner city, but they are certainly disadvantaged. It’s been a while since I’ve gone over this stuff, so I’m relearning some of it, but I have most of it down. I was hoping that some of you had some really good worksheets or learning materials I could get off the internet. I did a basic google search, but haven’t really found anything that great. Stuff we’re looking at: Factor trees, grids, Multiplication tables, exponents, factoring, basic algebra, Mean, Median, and mode, etc.
Any help would be appreciated. Thanks.

Answer: yeah
