Week 04 — 2026.09.22 – 09.27

Review week

22–27 September 2026 (the 22nd and 23rd are public holidays)

Nothing new this week.The 22nd is a national holiday and the 23rd is the autumn equinox, so there are only two sheets, Friday and Sunday.
The year plan makes the fourth week of every month a review week. What was met in week 1 comes back now, three weeks later.
Separately, each child has one Stretch sheet: September's units one or two levels up, PISA-style, crossed with science or social studies. Not marked, not recorded.

How to use them

How to use

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.
