Treats for getting good results

[wallypops]

My 8 & 9 year old have just had very good reports from school and good results too. Does anyone give their kids treats for good results? Or is this a slippery slope to be avoided. They are already thoroughly spoilt so I'm not sure that they need anything, but I am keen for them to keep up the good work. So if you do "treat" what would you consider reasonable?
Thanks for any ideas and thoughts.

We usually give then £5 each for their money boxes, this is if they have tried hard at school rather than what levels they have achieved.

I don't reward tangibly with presents, but praise high effort marks to the skies.

I try to praise the effort rather than the results as well. All I want is for them to do their best, however objectively good / weak their best turns out to be.

Maybe take them out somewhere they'll enjoy and spend time as a family?
