Wiping the table over after mealtimes.
Folding some of the washing (my girls like to help fold the washers and put them and the towels away with my help)
Emu parade for cleaning up outside in the yard.
My girls can be hit and miss with their 'help' and don't have a set list of tasks but they know they have to help Mummy when she asks them to do something and that being part of a family means everyone pitches in.
DD aged 2 is the most helpful of my kids, she will struggle to carry in a grocery bag from the car and look out if you try to stop her,lol. She races her sisters to try and beat them to get whatever I have asked them for,lol.
With teaching the value of money, I love using toy and food catalogues! DD's will ask for things and we can see how much money they have and see how they can't afford this and that...talk about how much they really want something etc.
At four it is normal to not have the concept of the value of things or to be worried about it. Mum and Dad have a money tree out the backyard...don't they? lol
