I think they're VERY lucky to have a teacher like you! Everything you've done so far is so wonderful! Pat yourself on the back, will you? The world needs more teachers like you.
I agree that you should let them process. But do check in with them, see if they have questions or want to talk about it, make sure they're not buying into myths about acceleration, etc. I think you have to be a "guide on the side" rather than a "sage on the stage" for this one. But I suspect they will want that guidance at some point!
