My GS child has work set every day on Ecoledirecte - do maths page x, print off these worksheets and do them, learn this poem, do this colouring in... It started off at roughly 2 hours a day (4 days a week) but has dwindled to about 1 hour (cos we're not pushing him to do longer). We have to send photos of the work but the teacher isn't very interactive.
My CE2 is drowning under work. He started off at 4 hours a day, 4 days a week and is now averaging 5-6 hours work a day, 4 days per week (except we end up spreading it over the 7 days).
He has 2 x 1hr20 zoom lessons a week (half classes) + the occasional extra 45 minute session to recite poetry. He has 2 or 3 tests a week on the website Socrative. He is doing grammar, spelling, writing, numeration, calcul, comprehension, history, geography, art (we have to post the pictures on the class blog), and English. I've possibly forgotten some things...oh yes, he's meant to read and do quizzes on Golibris, and learn his catechism and do sport videos and learn some songs for the June concert...
If school doesn't provide more, I'd buy those revision books CP to CE1 that are everywhere. Or those books that accompany the school year. That way you can revise all the CP work at least.
