Our cheap but fun job charts (we avoid the word "chore"). The 8 year old decorated his own. I drew pictures for the 4 year old. We came up with fun names for each job and use magnets we already have to mark when something is done. We discussed together age-appropriate tasks, but each had to have the same number, because fairness is extremely important to 8 year olds! It was fun and cost us nothing more than time!
