We have 5 children. Four of them are currently doing chores using these cards. We have been using these cards for about 8 years and we love them. They are great for non-readers. The chore card holders are flimsy, but I laminated the cards, punched a hole at the top, and my husband made a board with 6 nails across the middle and their name at the top. The chores that they are currently doing are stored on the last nail on the board (which toward the top of the board to separate it from the chores for that day). This makes the chore cards very easy to move.
My two daughters (13 and 10) are loving this chart, and doing chores without argument! I love the way the cards have a picture on one side, and describe in detail how to do the chore on the other. It is great for all ages. I have to admit that it has gotten me organized also, and has freed up some of my time since the girls are helping out and have lightened my load without complaint. I also like the fact that they are careful with spending their "Mom$" and we all look forward to opening the chore store. When we are out shopping and they ask for something, we discuss adding it to the chore store and there are no arguments if we decide not to. I also like the fact that I am not the bad guy anymore -- the chart shows them what to do and if they don't do it, they start over the next day. They are taking responsibility for doing it right the first time. I wish it were a bit more durable, but I have doctored it up with bright colored duct tape around the edges and we have made it our own.
My kids love this product. I usually make our own charts, but I like the pictures for little ones and a chart for each child. The children love the Store Money (which we use for activities rather than real money) For large families you may need two sets. Since the individual charts are a little flimsy, I'm looking for a way to put the charts on one firm board. It's too soon to say how useful it will be for our large family.
This has been the best motivator and only chore chart out of many that I have tried that actually worked with the kids. It is easy to use and the kids have fun seeing their jobs each morning. I love that it has the directions on the back of each card so my older son can just read the card and do the job. It is great! The only problem I have personally is remembering to stock the chore store!
