Singapore's CWP as supplement??

[Homemama2]

I have a 1st grade ds. We are using Rightstart B with him, and so far he really gets it! :D So I was thinking of adding in Singapore's CWP to challenge him a little....but I would really like some other opinions. Is CWP a good supplement in first grade? Or should I wait because Rightstart might get really challenging later on?? Thanks!!:001_smile:

I usually do CWP a year behind (book one in 2nd grade, etc.) because it's really quite tough.

I didn't find Challenging Word Problems for the first grade worth doing because the student isn't required to make any decisions. The problems are grouped according to operation so that all of the problems in a topic are all addition or all subtraction. All three of my children would mindlessly write out a subtraction sentence without really paying attention to what the word problem said.

In the second grade things change. In the second grade Singapore students learn how to add and subtract with regrouping and the 2,3,4,5 multiplication and division facts. The first set of problems in a topic require one step to solve and since they are the relatively easy ones I take this opportunity to teach how to model the problem using bar models.

The second set of problems in a topic are "challenging" and require two steps...in later grades the ordinary problems require two steps and the challenging problems will require three steps to solve. You'll also be grateful you took the opportunity to teach bar modeling in the second grade back when it was easy to figure these things out.

I will be starting my second grader (main math is already Singapore) on Challenging Word Problems just as soon as she learns to subtract with regrouping. (We got a very late start with school this year for sundry reasons.) A second grade word problem involving addition and subtraction looks like this: Jerry has 45 marbles. John has 19 more marbles than Jerry but 18 fewer than Mike. How many marbles does Mike have?
