The idea is that your child receives a star each time they achieve a set target. You decide what your child has to do... and if it gets done, you reward the good behaviour with a star. Once your child collects a set amount of stars, they are rewarded with something that you have already agreed with them. For many children, the fun of receiving a star is reward enough. It's that simple! Each week, you and your child set out weekly tasks and choose a reward.
