How old is your child?
When i was about 8, i really loved doing profit and loss statements and t shaped balance sheets. I still find it relaxing. sometimes i make up that i received x amount from a donation or i earn y amount from an imaginary job and work out how much morgage and tax i would have to pay on a z amount home and a w priced car. ect. IT IS FUN!
Maybe take your child to a basic accounting course at night school or get some accounting texts if they are old enough.
