My kids are 8.8 and 6 but the 6 year old is more like a 3-4 year old. I have better luck assigning things that aren't related to their own stuff. 8 yo ds cleans the bathroom (I have specific instructions posted) scoops the litter box, feeds the cat, and dusts the tv area, 8 yo dsd cleans under and on the kitchen table dusts a bookshelf, waters the cat, and and cleans the shower, 6 yo ds wipes down the toilet every night and helps put things away but I have to guide him with that.
After they do their basic tasks for the night they can do extra chores for $$. 8 yo ds is mostly motivated by this but it comes and goes. Steam cleaning the kitchen floor is his favorite chore to do.
