# Key to fractions, decimals...

## Recommended Posts

Are these supplements for upper grades or any children struggling with those concepts?

I just had my 12 year old work through key to fractions as a review. I think she probably could have used them when she was first learning fractions at a younger age, but it is a bit dry and there are more interesting ways of learning fractions the first time around. It does go through fractions conceptually from beginning to end in the four workbooks.

I am not sure it would have been enough built in review for her if it had been the first time around, but she does need a lot of review in math. For a kid that just gets stuff and doesn't forget it then it might be enough. We have not used decimals yet but I plan to use those as a review as well. I think most people use them as a review/supplement and not as a full curriculum but I could be mistaken!

I used them with my 7th grader who totally gamed the system with Teaching Textbooks and didn't know fractions at all. I really liked them. I think it is thorough and does a good job explaining. I wouldn't use it as a primary curriculum, though.

I think they are supplements for any child struggling with the topics. I wouldn't use them to introduce those topics, but I have had a child (11yo) use them to circle back through and solidify when things seemed to be slipping.

I was planning in using it as supplement for those topics. I have 2 5th graders and a 3rd grader.

The "usual" age for these is grades 4-8, either as a supplement while learning the concepts, or for those students needing a review, or for those students needing to "get solid" with the topics if the topics didn't click the first time around. Also useful for high school ages as a gentle/incremental remedial resource. We used the Keys to Fractions, Decimals, and Percents as a supplement to the "spine" math program in grades 6-7 with DS who struggled a LOT with math (mild LD with abstract math topics).

Because the series does include a lot of work with all 4 functions (add/subtract/multiply/divide) your 3rd grader may be a bit young for these, unless the 3rd grader is already very solid with all 4 functions, esp. multiplication and division.
