I told DD13 that I will give her £10 per book she finishes and £1 if she does 30min of maths per day; she seems very motivated. In addition to her school work.
She does her school homework and tutor work but apart from that doesn’t do much and is a bit behind a school. She doesn’t really get pocket money but we buy what she needs/ask within reason and she has money from ocasional pet sitting.
I have always been of the idea that you study and help in the house because it is your responsibility and you don’t get paid for it; but I am hoping that she will develop a love of learning and reading with this additional motivation.
