Had a great first meeting with DD8's teacher today. They're going to group kids by ability across classrooms for math and reading. All math and reading instruction will take place in the small groups, and each group will be able to progress at its own speed. The math group is starting out below DD's level (and below the level of at least one of the other kids in her group), but it should be able to rapidly move through the review work and into the fun new stuff. DD8 isn't as advanced as DD10 (she's only 1-2 years ahead, rather than 4+), so this should be perfect for her.
