Are they using Everyday Math program? There are two types of math programs being taught in schools now: traditional and "new-new" or "reform" math.
These are websites to inform parents about the cons of New-New math:

My school district (Conejo Valley Unified SD) uses EM and I'm not happy about it. The more I learn the more I get angry. Save Our Children From Mediocre Math is a local activist group. The mom who created the site pulled her son from the district. (She's not the only one.) I'm glad she's still active and trying to inform other parents about it.

There was an article in the LA Times a few weeks ago about Singapore Math program being taught in an LA school and how kids are excelling with it. Singapore & Saxon are traditional programs. You can look up these topics in Wikipedia.

My 2nd grader has horrible penmanship, so I went to a local education/teacher supply store to buy products. I was chatting with the salesperson (who was also one of the tutors) and she said she taught children from all the local private, public and nearby districts (which BTW don't use EM). She said the EM is awful. They jump and switch from subject every week (other programs are more linear) and that she reviews the previous weeks work before they start on the current week, which helps her students. Now I know that's what I have to do.
Watch the video. Ask your school what math program they are using. Ask other parents in your school how they are doing with math.
