Begin by listing all of the tasks that need to be done on a daily basis. This list should include but is not limited to: Wash dishes, sweep kitchen floor, make bed, tidy bedrooms, and tidy family/living rooms.
Now list things that need to be done on a regular basis (every couple of days or once a week) like vacuum floors, mop floors, dust, laundry, clean bathrooms, deep clean kitchen, etc.
Once you have your housework listed in those two groups it is time to divide the housework up among the days of the week. You have your daily chores and those never change but now you need to assign the "regular" jobs a day of the week. For example:
Tuesday: Wash kids laundry, vacuum
Wednesday: Wash adult’s laundry, mop
Thursday: Dust, go grocery shopping and run errands, vacuum floors
Friday: Clean bathrooms, wash bath towels and sort through papers.
Saturday: Clean bedrooms, wash bed linens
Sunday: Enjoy the day off.
If you have any questions don't hesitate to ask.
