I would try to talk to the teacher and ask a few open ended questions before jumping to a conclusion. Our school board's system had a bunch of drop down menus that they pick things out of and it is often hard to decipher the edu-speak. They will say things like "X should work on mathematical problem solving skills with numbers 1-20" because that is what is next up in the curriculum and since they haven't tested it yet they have no idea that X can handle far beyond 20.

I will also say that our more confusing report cards were for our DS who we now know is gifted/LD. Not to say that your child is 2e but it is something to be aware of as a possibility depending on the school's responses. I know it wasn't really on our radar when we started this adventure but we were really lucky that we figured it out pretty early (grade 1). I had no clue about the huge variety of LD's out there.

Good luck!
