Every Sunday night before going to bed, roll 2 dice with your kids: Do this for 52 Sundays & you could see how much is accumulated at the end of the year:
If the Dice shows:
* 2-5 – Save 50/- in the piggy bank
* 6-10 – Save 100/- in the piggy bank
* 11 & 12 – Save 500/- in the piggy bank
Possibly, you can have 2 piggy-banks one for you & one for the child (if there are two children, one each) & see who has accumulated more at the end of the year.
*At the end of the year, collect all the money together – spend some, save some & donate some…
