We got the boys' a chore chart from Crafts Direct a few weeks ago. I used a 40% off coupon and it really wasn't that expensive then. We finally found a place in the hallway to hang it up. It is right in between both boys rooms.
I picked up a few Mario Kart and Spongepop collectors cards as some rewards if they follow through on all of their "duties" for the next week. We'll see which boy wins the cards, so far Morgan is one up on Aaron for completing some chores tonight!
