Week 03 — 2026.09.15 – 09.20

This week's sheets

15–20 September 2026

This week uses last week's tools.There is no new unit. The same multiples and factors, the same place value, the same division — found inside a sentence and then used.
What gets harder is not the arithmetic but spotting what is being asked.

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.
