I plan out all our afterschooling and prioritize and some subjects are looped. My son is in Gr.3 and used to afterschooling. Piano and flute practice every day: 15-45 minutes depends on the load on that day. Math is everyday15-30 min but mixed up with puzzles for logic (he loves them). Third language: reading and writing 15 min each and rotates, 3-4 times a week. I read during his breakfast in 3rd language stories, science, fun books. He reads before bed 15-20 min in English (first language). He does his school homework (2nd language) right after school couple days a week, the load is minimal. He plays competitive soccer 3 days a week. The top priority is school homework, 2nd is piano, 3rd is math, and after the rest on the loop. He is home at 3:00 and free to play for an hour, we start at 4:00. Dinner at 5:30-6 and he has free time. We do the rest 7-8 pm or soccer. At 8 he goes to bed. Weekends are mostly free or catch up on what we didn't have time to do during the week, plus friends and family visits, museum, concerts or outdoors.
