Three drills
Notes on arithmetic practice, and three drills for children
Carrying, times tables, missing-number problems: where arithmetic practice actually gets stuck, written up alongside what building the drills taught us.
The drills cover elementary-school arithmetic, kanji and proverbs. Each round is 10 questions, about three minutes; the problems you find hard come up more often, and no sign-in is needed.
Notes on where arithmetic practice actually gets stuck, written to be useful whether or not you use the drills.
A child who answers 2 + 5 can still stop at 7 + 5, and it is not about the size of the numbers. Carrying, broken into the three steps it really is.
Treat a x b and b x a as one fact and the pile halves. Which ones are last to stick, and what is gained by taking one table at a time.
A box plus five equals twelve wears the face of addition and asks for subtraction. It needs the equals sign read as a balance, not as a place to write the answer.
Wrong, slow, or not seen for a while - three faces of weakness weighed into one number, plus what has to be added so that practice stays bearable.
Where the four- and ten-second marks came from, and what to do about the case that timing children makes them afraid of maths.
Daily Math
Addition, subtraction, multiplication, division — 42 types in all.
7 + 5
The arithmetic taught in elementary school, including problems with a box (□ + 5 = 12). The faster you answer, the better the mark you get.
Daily Kanji
All 1,026 characters of years 1–6 — about 5,750 questions.
アイドル歌手
One kanji in a short phrase is the question. Some ask for the reading, others for the character itself. Kanji not yet taught at school carry small furigana.
Daily Proverbs
130 Japanese proverbs, asked in three different ways.
犬も歩けば □
Proverbs are asked three ways — fill in the blank, match a meaning, or match a scene. The aim is knowing what a proverb means and when to use it, not handwriting.
Each app remembers what you got wrong, or have not seen for a while, and weights the questions accordingly — so you do not just repeat what you are already good at.
The pictures you win are collected and can be looked at again any time. They never disappear.
How many you solved, how many you got right, and how long you took — kept day by day, with a view of where the weak spots are.

Match Record
This one is not for children. It lets a school club or team keep its match results — score, outcome and video — season by season, and share them with its members. Free to use, like the three above.
Each is published separately, and all are free to use. Privacy Policy Contact
