1. Regular chores automatically go along with being part of a household–kids and adults alike have to do their part because that's how it works together. They are not optional, and they are not a means to a reward.

2. Allowance is given for the express purpose of learning about how to use money. In a sense, a small part of the family financial management is moved into the hands of the child, and this role expands as the child gets older. The amount is determined by what you currently spend on the item yourself. Say, start with toys or incidental treats. Figure out how much you spend on these things, averaged over weeks, and divert that money directly to the child (and stop buying those items yourself). This isn't “free money”–it's distribution of responsibility. It sounds similar to your “teenage incidentals” budget.

3. Charity and savings can be worked in the same manner as discretionary income, with the same principle of diverting money in amounts you would have spent yourself, e.g., your child is given responsibility to determine how to spend 5% of the money you budget for charitable giving. Making all of it transparent like this makes more sense, I think, then telling a child arbitrarily, “I'm going to give you $5 this week, and $1 has to go to savings, and $1 to charity.”

4. Finally, I still think there's room for paying for “bonus” chores, which is where that price list might come in. These would be chores that are not the child's regular responsibility, like washing the car, or cleaning the parents' bathroom, or doing the parents' laundry. This maintains the opportunity to reap rewards for work and set goals.
