Kfamily Posted February 12, 2009 Share Posted February 12, 2009 (edited) I have decided for various reasons that our R&S grade 6 textbook is not enough for dd in 6th to get her ready for Chalkdust PreAlgebra next year. We have been using Singapore as a supplement but we are only in the middle of 4A. If we stop R&S completely (and not finish the book) we would still-even if pushing hard and over the summer- most likely just finish 5A and maybe start 5B. I bought Challenging Word Problems 4 and wanted to add this as well. Our school year begins in mid-late August so this would be about 6-7months to do all of this. I think we can double up a lot in the beginning because she has seen everything in 4 and a lot in 5. Is this enough for CD prealgebra?

Mary in GA Posted February 12, 2009 Share Posted February 12, 2009 First, I don't know anything about Chalkdust Pre-algebra so I won't be helpful there. However, a student finishing SM 6B is prepared for algebra 1. We have not used any pre-algebra texts, but the ones I previewed contained word problems that were really simplistic compared with Singapore. I would venture to say that finishing the 5 series would be enough for pre-algebra. You could speed it up by skipping some of the lessons on tesselations, graphs, and some geometry.

angela&4boys Posted February 12, 2009 Share Posted February 12, 2009 Just a gentle nudge to encourage you to post this on the high school board if you didn't already. You may get more responses there. :) Quote Link to comment Share on other sites More sharing options...
Kfamily Posted February 12, 2009 Author Share Posted February 12, 2009 bump p.s. I did x-post this on the highschool board:001_smile: Quote Link to comment Share on other sites More sharing options...
Kfamily Posted February 13, 2009 Author Share Posted February 13, 2009 still would like some advice...:001_smile: Quote Link to comment Share on other sites More sharing options...
runningirl71 Posted February 13, 2009 Share Posted February 13, 2009 I'm bumping this up again. We're in Singapore 5 and will be starting Singapore 6 in the fall. I've heard that, if going straight into Algebra I from Singapore 6 there is a great huge leap in concepts. That has made me think a pre-algebra program would be necessary to bridge the gap. No?

Stacy in NJ Posted February 13, 2009 Share Posted February 13, 2009 Hmmm, it may depend on the maturity of the kid. My ds finished 6B in 5th grade. I opted to NOT move right into algebra. We're using this year (6th) as "pre-algebra" and "challenge math" using various resources. I didn't feel ds was ready for the big thick textbook yet. Next year we'll begin Algebra. There are many topics not covered in Singapore that would be considered typically "prealgebra", for example; integers and exponets. Some Algebra programs cover these with enough depth, but others assume some prior knowledge. Unless you have a really strong math student, I just wouldn't move from Singapore 5B into CD prealgebra. It would leave several gaps. Quote Link to comment Share on other sites More sharing options...
langfam Posted February 13, 2009 Share Posted February 13, 2009 (edited) You could work through Lial's BCM which is excellent for covering basics. Then use CD Prealgebra. I know lots of folks here use Lial's BCM as a Prealgebra course, but I really like CD for Prealgebra because I think if gives them more exposure to algebra-type problems whereas I don't see that in Lial's. Many kids can jump from Lial's BCM to Algebra I, but I prefer for mine to have year of "lite" algebra. http://www.amazon.com/Basic-College-Mathematics-Developmental-Paperback/dp/0321257804 Edited February 13, 2009 by langfam Quote Link to comment Share on other sites More sharing options...
