How much allowance, and where does it go?
Chores times a rate, or a flat weekly amount, then split into three jars. Kids learn faster from the split than from the total, so the split is the point.

Per chore or flat?
Per chore teaches that money comes from work, and it makes the tracking honest: no chore, no dollar. Flat allowance teaches budgeting a fixed income, which is closer to how adult money works. Many families do both: a small flat amount for being part of the household, and paid extras for jobs above the baseline. The full-week bonus above is the middle ground, it rewards consistency more than any single chore.
Why three jars
Save, spend, give is the split most family money educators use because a kid can see it. The save jar is where the first lesson about waiting happens. The give jar is small on purpose; the habit matters more than the amount. Spend is theirs, and the rule that makes it work is that you do not veto what they buy with it.
Make the save jar do something
A jar of coins does not grow. Once it hits $20 or so, move it to a kids' savings account or a custodial account, and show them the interest line. The yearly save-jar number above is a good target for the first "we opened an account" moment.
A budgeting exercise, not financial advice. The three-jar split is a common approach from family money educators; any split that you actually stick to works.
