I agree with Trill in that if he already understands that much then he'd probably get the concept of earning, however I reckon that not quite three is still to young to have to earn anything. He might understand that you will give him coin if he does stuff you ask, but does he understand the difference between 10c and $1 and what that really means in the overall scheme of things?
And, would that lead to 'well I'm only going to do xyz if you give me money"?
But that also maybe because I'm not a fan of pocket money in exchange for 'chores'. I believe we all live together, so everyone can contribute in their own way, it makes our house a nicer place to live. Pocket money fair call, because I can, for no other reason

I'm all for teaching the value of money, but they are only little for such a short time and think you are everything for that same amount of time.
