Short and often: 10 minutes a day · Lập trình với Martin

Ten minutes a day beats an hour once a week. How to build a small practice that lasts.

Ten minutes a day beats an hour on Sunday

If you cleaned your teeth once a week for a whole hour, it would go badly. With maths it is the same — only it does not show on your teeth, but on a test.

The brain learns by repeating, with sleep in between. Every night it tidies what you trained in the day. Ten minutes a day means seven tidies a week. An hour on Sunday means one. That is why short and often wins, even when it is less time in total.

There is a second reason: ten minutes you can last with full attention. An hour you cannot. And practice without attention is like lifting an empty weight.

Today you will build your ten-minute practice: when, where and what exactly will be in it. Small, concrete, the kind that survives even a week when you do not feel like it.

Tereza has a test on Thursday. On Wednesday evening she sits an hour and a half over the notebook, her head smokes and she forgets half of it by morning. Jonáš writes the test too — but in the evening he plays football and goes to sleep in peace.

His secret is not talent. Every day after his snack he does ten minutes of questions. Kitchen table, a parent’s phone alarm, paper. In two weeks that is fourteen small practices. Tereza’s Wednesday race is one big one. They will both write the test — but Jonáš will remember it in a month. Tereza until the weekend.

💡

Stick the practice onto something you already do every day: after a snack, after you get home from school, before dinner. Same time, same place. Then the habit starts itself and you do not have to fight “I do not feel like it” every day.

What ten minutes that work look like

Ten minutes is not “I stare at the notebook until the alarm rings”. It has a shape.

Minute 1: warm-up. Two or three totally easy questions you can do with your eyes closed. You start the head and begin with a win — that is not cheating, that is a start.

Minutes 2 to 8: the main practice. One single topic. Addition to twenty today? Then only addition to twenty. Mixing five topics into ten minutes is like training football, swimming and chess in one break. Count on paper, with a method, as you know from lesson three.

Minutes 9 and 10: reading clues. Go through what did not work. Read each mistake as in lesson two and write it on the My clues page. No mistake? Write the topic and the date — that is a clue too, a good one.

And one golden rule: stop while you still enjoy it. Do not stretch a good day to half an hour. Tomorrow you will have something to look forward to — and a habit you look forward to lasts.

Example 1: Jonáš’s Monday

Jonáš’s slip: “Monday, after snack, topic: subtraction to 20.”

Warm-up: 10 − 5 = 5, 8 − 4 = 4, 9 − 3 = 6. Done in a minute, the head is going.

Main practice, for example 14 − 6. Method through ten: first he subtracts 4 to reach a round ten (14 − 4 = 10), then the rest: 10 − 2 = 8. He split six into 4 + 2 and went through ten. Same for 13 − 7: 13 − 3 = 10, 10 − 4 = 6.

Reading clues: at 15 − 8 he wrote 6 instead of 7. He writes: “I split eight wrongly.” End, ten minutes, paper in the drawer.

Example 2: a weekly clue on paper

Sofie wrote the days of the week on paper and makes a tick for each practice she finishes. After two weeks she reads: Mon ✓, Tue ✓, Wed —, Thu ✓, Fri ✓, Sat ✓, Sun —.

She counts the ticks: first week 5, second week 6. Together 5 + 6 = 11 practices out of 14 days. She also sees a pattern: Wednesdays drop out, because she has a club until evening.

The fix is not “try harder on Wednesday”. The fix is to count on Wednesday morning at breakfast. The clue on paper told her exactly where the plan creaks — just like a mistake in a question.

⚠️

You skip three days and then do forty minutes to catch up? That is not catching up, that is the Sunday hour in disguise again. Leave a missed day alone and the next day do a normal ten minutes.

Practice: now you do it 🎲

Now try it for real. You will see all the questions at once, like on paper. Bắt đầu with ten. When it goes well, add more.

The first official practice: addition and subtraction to 20, on paper, with the method through ten. Five right in a row.

Practise the questions

On paper: your practice slip

A plan that lives only in your head disappears in a week. A plan on paper survives.

Write a practice slip: WHEN (what you will stick it to — after a snack? after school?), WHERE (which place — your nest from lesson three?) and stick it where you will see it.
Draw a table for 7 days with a box for a tick each day.
Do the first ten-minute session right now: a minute of warm-up, seven minutes one topic (the worksheet is fine), two minutes reading clues.
Make the first tick in the table. One tick looks silly — in a month there will be a row of them and that is not silly.

Now you 💪

I know which daily activity my practice is stuck to and where I sit.
I can say the shape of ten minutes: warm-up, one topic, reading clues.
I have xong the first practice and the first tick in the table.

✅

Done when: The slip is up, the table exists and the first tick is in it.

What to take from this lesson

The brain learns by repeating with sleep in between — that is why daily, not once a week.
Ten minutes with full attention beats an hour with half.
Shape of the practice: warm-up, one topic, reading clues.
Stop while you still enjoy it. Tomorrow has something to look forward to.
Do not catch up a missed day. Just go on.
