What resource can I use to review/solidify basic math (percents, ratios, etc) with 9th grader?


Recommended Posts

We're into Algebra 1, but I want to at the same time do some review each day on previous topics to help her remember them and solidify them and keep them fresh.

 

I'd really love something that has spiral practice of the basic topics-percents, ratios, decimals, higher level fractions, statistics/probability (like whisker plots, etc.)--not so much a topic heavy thing like the Keys To...series.

 

Any ideas? Online or book form is fine. Thanks!

:iagree: Have dc do the Khan PreAlgebra Mastery Challenge.  They will get a mix of problems covering all of PreA.  If they get them right, they get fewer problems further apart, if they miss some they get more problems on that topic.  I think it's a good way to keep things fresh as you are moving on into new challenges!
