We've just been using the system for a couple of weeks now and it has been brilliant. My 5 year old is loving the 'belt' incentive and it keeps him wanting to do it every day to get to the next level. He doesn't see it as homework, I think he just views it as a challenge which he loves. What we like is that we're able to give him useful/educational screen time and it seems to be enough to keep him happy without overdoing it. We have the posters up in his room and he's quick to point out when he needs another sticker. We'll be telling all our friends because so far we can see his confidence growing, particularly with maths, as the way it's taught has meant he's now looking at numbers in a very different way.
