I have the opposite reaction. LOL I hate their 2nd grade history but think the math is ok. LOL It seems to follow the math curriculum for our public school so maybe that is why. Just goes to show that everyone needs to look into more than one curriculum before deciding. What math program are you thinking of going to?
We are going to go back to Saxon. I used it last year to after school my son and he did pretty well with it.
There are 2 problems with K12. The first one is that the teachers guide gives absolutly no instruction as to how to teach the concept. (I've heard this complaint a lot from other users.) For 2nd grade this wasn't really an issue, for 3rd grade it has been. I've spent a lot of time on the internet learning how to teach concepts. Pretty sad IMO considering that math are strong points for both me and my son.
The other problem, and it's what's leading to his frustration right now is that they spend no time working on learning the facts tables. You have one lesson on each # and then it's done. It was litereally 2 weeks and then they are expected to be able to do these long problems that require knowing them. We are going to finish the lessons that we need to. (Picking and choosing the ones he can do w/o frustration.) Then we are going to spend the summer working on all of his facts tables.
There is also no spirialing/review. They teach a concept and then expect that it is mastered.
