Mom2three8383 Posted February 16, 2017 Share Posted February 16, 2017 Are these supplements for upper grades or any children struggling with those concepts? Quote Link to comment Share on other sites More sharing options...

Peaceseeker Posted February 16, 2017 Share Posted February 16, 2017 (edited) 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!

KrissiK Posted February 16, 2017 Share Posted February 16, 2017 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. Quote Link to comment Share on other sites More sharing options...
Miss Tick Posted February 16, 2017 Share Posted February 16, 2017 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.

Mom2three8383 Posted February 17, 2017 Author Share Posted February 17, 2017 I was planning in using it as supplement for those topics. I have 2 5th graders and a 3rd grader. Quote Link to comment Share on other sites More sharing options...
Lori D. Posted February 17, 2017 Share Posted February 17, 2017 (edited) 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.
