DD2 is 9 nearly 10 and she gets $10 a fortnight, this is for unpacking the dishwasher usually once a day - but sometimes twice a day, bringing in the wheelie bins, keeping the cats water bowl topped up and washing her 5 year old sisters hair in the shower. At times we might ask her to do other odd jobs here and there.
She has to do these things without complaining and when she is asked - if she complains or doesn't do it when asked she gets a "strike", one strike equals 50 cents, and this is deducted off her fortnightly amount, but she can also earn extra if we think she has done a particualry good job with something, or done something without being asked etc.
Keeping her bedroom tidy, cleaning her teeth and getting ready for school is not part of her pocket money - it is something we expect of her as a member of the family.
DD3 gets $4 a fortnight - she doesn't really understand the concept of money but she has a money box and a school bank account. Her job is to feed the cat dry food and hold DD1's hand when I brush her hair in the mornings (DD1 has a disability and HATES having her brushed, but loves it when her little sister holds her hands!). We expect her to get herself dressed for kinder and put her lunch box and drink bottle in her bag as well as keep her room tidy - again these are things we just expect of her, not things that are done for pocket money.
Both girls are expected to put money in their school bank accounts each week. DD2 likes to keep about $10 in her money box for extra's and the rest she saves. At the moment she is saving up for an ipod. She has $185 so far, when she gets to $250 we will make up the rest.
At Christmas time we also go halves with them in a present for the local Giving Tree - they have to use their own money for this - and they get to choose the present and how much is spent. So far they have been really good at picking out things they would like to receive, and not too cheap either.
