The mode is the most common number - the one which occurs the most. I remember this word by thinking of 'mode' being like fashion - so it's the most 'fashionable' number, ie the one that's around the most!

So if you look at your numbers, the most common are '9' and '10' , as they were each scored by 4 children. So 9 and 10 are both the mode.
