Our son is at Montessori and now in Week 7 of Grade 7 online/modular learning. They have an online session with teachers each morning, much as described by Pompolino, then it's up to pupil and parents to ensure the weekly module is finished by Friday pm to exchange for the next week module. Depending on your child's motivation (our's has little - mother & son just had another bout of nagging and tears), this can be a time-consuming and stressful exercise compared to dropping them off at school and letting the teachers get on with it, because of the potential for distractions at home. Reliable internet connection and ability to go to the school to exchange modules on a strict timetable is important. On the whole it's going fairly well, although there's yet to be any feedback from teachers on performance. I never was any good at algebra.
