Nathan's chore money

A few weeks ago Nathan told me he wanted to get a job at the supermarket. I asked him why and he told me, so he could earn money to buy the Lego Star Wars video game. I told him that was a good idea, but he couldn't work at a supermarket. He suggested he could do chores here at home to earn money, I jumped on that idea. He has been helping me everyday with different things around the house. He has helped put the silverware away from the dishwasher, watered my plants, vacuumed the couch, set the table, sweep the floor, dusted and others. He is a pretty good helper. We pay him $.25/chore and most days he wants to do two or three chores. Some days he will even wake up and ask what chores he can do. Although, he has changed what he wants to buy with his money, now he wants to buy Lego Monster Fighters- Lord Vampires Castle ($120.00). He has $11.25 in his bank so far, it might take a while but we are very proud of him!
