Three things motivate children here, in this order: being good at it, being seen doing it by people they love, and a routine so ordinary that it is not a daily decision. Rewards work for a few weeks and then become the price of reading, which is worse than where you started.
Why rewards stop working
A sticker or a pound a page works because it is new. When it stops being new the child does not go back to reading for its own sake -- they wait for a bigger reward. You have accidentally taught them that reading is the unpleasant part and the sticker is the point.
This does not mean never celebrate. Finishing Qaida is worth a celebration. The difference is between marking something that happened and paying for something to happen.
What works instead
Competence
Children like what they are good at. Every visible improvement is motivation, which is why a teacher who corrects well does more for motivation than any chart.
Being heard
Let them recite to a parent, a grandparent, at the end of a family dinner. Five minutes of being listened to beats a week of being told to practise.
Routine
If the lesson is at the same time every day, nobody has to decide anything. Motivation is mostly the absence of a daily argument.
Meaning
An eight year old who knows what Surah Al-Fil is about reads it differently from one who has only ever been corrected on the letters.
Things to stop doing
- Comparing them with a sibling or a cousin who is ahead.
- Using the Quran as the punishment: “no tablet until you finish your sabaq”.
- Making them perform for guests.
- Reacting to a bad lesson. The child already knows it went badly.
