I have just learned that DD's math curriculum is Common Core- based. For some reason I am hating the way the book is written this year when I had no problems with it last year (same series). It's not about the actual problems, but poor writing style. However, I think the pace and material covered are pretty good. DD is working exactly a year ahead.
Through Googling, I have learned that this book is hated by teachers for moving too fast and being too hard. So maybe not great for most kids, but it may be that Common Core is indeed a step up in terms of rigor? (rigor rigor rigor)
