Thanks!

We haven't done much sixth grade stuff yet.

The school uses Singapore. They finished 4A together last school year. They also have finished grade 5 on ALEKS.

We are doing Beast Academy 4A and 4B this summer, and they attend math club/team.

They'll be in the same class next year, with an excellent teacher who is willing to push them. Looking ahead at the Singapore placement tests, I am thinking that they will be able to jump into 5B in the fall. I hope they can do the Singapore workbooks two days a week and work on BA on the other days. I feel like that will keep them learning and challenged without just racing through the core as fast as possible, while still placating the principal that they're getting the district's chosen curriculum.

Then the next year, they should be adequately prepared to start AOPS prealgebra as fifth graders.
