Chores Revisited

I'm back! For today anyway - it has been a really long time but I just felt like I wanted to record this 'new 'leaf' for today.
I had a revelation this morning. Our weekly chore plan is not working and it is about to make me crazy. It is terrible. We have been trying to do "Zone Cleaning" for the past 8 months. Most of the time the zones go untouched and when we do get to it we panic and do more than one zone at a time. So - clearly this is not working for our family. I just received my 5th Module for my studies yesterday and I need to get my Family helping me to manage so that I don't loose it from too much to do.
One thing that is working is the daily chore plan. They each have the exact same chore to do each day - each meal in fact and they are totally doing this. When both mom and dad are out, for example, they do it like a well oiled machine. So if this is working - how can I adapt this to make it work for our big weekly cleaning? This is the plan. Give them ownership of one area of the house so that they can get good at that one thing - that is why the daily chore plan IS working. Each child is still responsible for their own rooms but now also a different area of the house - 12yodd takes care of living room/entrance way, 9yods bathrooms and hall, 7 yodd recroom - then the two little mermaids get to just do their room and the chalkboard. I am starting another Tidy Up chart for them too so that they can stay more on top of the daily cleaning up of their toys - man they can make such a mess!
The three oldest are responsible for cleaning, vaccuuming, mopping, dusting whatever area it is before Saturday at noon. They can do it earlier in the week if they like, but it has to be done by then. First of course we are in training mode - it took longer today because of stopping and teaching my son how to clean a toilet and scrub out a tub, for example. So this is going to take time - I get that. There may be tears, there may be struggles, but is it just me or is it possible for our house to be cleaner with less work from yours truly?
When I go to study in the evenings, knowing that the house is tidy and clean is a huge factor in whether I get lots of work done or not.
Let's see how it goes!
