Checking in on math instruction

By request, a thread for parents to talk about math instruction, especially at the elementary level. How are your kids doing in math? How is the pacing? Are some classes having trouble with the curriculum, either finding it inappropriate for the age, awkward, or that too many students are behind while others are ready to keep going? Thoughts on what parents can do to improve the math instruction?
