Week 03 — 2026.10.13 – 10.18
Tue 13 – Sun 18 October 2026
Print one day at a time, or the whole week in one go — it is the same content either way. Neither one contains the answers. Those are the last card, printed separately.
Averages and decimal multiplication and division, from practice to word problems and applications. Wednesday: average internet speed. Sunday: average speed (the average of a round trip is not the average of the speeds), corrections and one puzzle problem.

For a parentThis week's answers for Younger son · Grade 4 — a parent should keep them.
Tuesday, Wednesday, Friday, Sunday — four sessions of forty minutes. 5 min arithmetic, 20 min new material, 10 min corrections, 5 min kanji.
Print a single day or the whole week. Each framed section is one A4 sheet, and a day comes to exactly two or four of them — one or two pieces of paper if you print both sides.
The answers are a separate page, for a parent to print alone and keep.
The three language versions are the same problems. There is no need to do the maths three times. Solve one, and read the other two. Knowing the problem already is what makes the unfamiliar language guessable.
