Thanks for all of the ideas. Just FYI, here's what i went with.....
I have been letting the kids get hot lunch once a week, which is $3. So, I gave them each $12, and said there is your hot lunch money......if you eat out less, you have more cash....if you want more hot lunch, you pay for it. It will also stop the little manipulation of "Oh I forgot my lunch so I HAD to get hot lunch". I told the kids, you get hot lunch, you pay, whether you planned it or not.
Oldest ds (13) got $25 for the month, dd (11) got $20 and ds (8) got $15. I have to do it once a month......I cannot keep up with once a week. And since the money is designed to teach money management, getting money once a month can help with that.
I also chose 9 basic chores that I really wanted done, that need to be done daily, and are about equal in energy and effort. I asked each child privately which chores they preferred, and it actually worked out. I also choose my three "pet peeves" (hanging up a towel after a shower/bath, clothes on the floor, and having school and after school items ready the night before) that I wanted each child to follow through with.
So, I told the kids that the money was there for them to use, but I would fine them if the chores weren't done. Essentially, I am SO tired of hearing kids argue over who's turn it is to feed one of the two dogs, or change the cat box, etc. So maybe fining kids isn't the best thing for teaching money management (I actually tend to believe more in the idea that chores are what are needed when you are part of a family, and that allowances are for teaching money management), but I REALLY NEED IT FOR MY MENTAL HEALTH!!!!!!!
Hopefully this will help out.
I figured I'd deal with the whole clothing and school supply thing for ds in May or June, after he graduates. He doesn't need it now, so if I can just get a basic allowance system in place, I'll be happy.
