A challenge is something hard that you cannot do. But you will get it at some stage.
I have something hard and that is division. But I will try harder than before and I will progress.
Next week is cross country and I hate running but each day I get fitter.
In class at reading time, there is this program called Lexia core 5 and I am on level 10 and I need to move levels so I must practise more.
If I try hard I will accomplish all my challenges.
