Currently I am helping 2 kids with their maths preparing for this years 11+. I have problem of making quite a bit of careless mistakes. Sometimes may be lack of effort in reading the question and rush to give the answer and some other time looks like a bit of over confident.
How could I persuade them to get their full effort in doing their work?
When they have done a practice paper and are reading back over their work, maybe offer them a small bri... I mean an incentive for every mistake they spot and correct (within the time allowed?) Perhaps a sweet or sticker or something. I think I might have to do something like this with my DS, as he has a tendency to rush and not bother to check things.
