We email you a fresh chart every morning, already filled in with your kids and your week. You print the one that came. During the day, you tell Siri what got done. By morning, tomorrow’s chart already knows.
The paper stays. The bookkeeping is ours.
At four, the chart is about repetition, not productivity. Toys in the bin, dirty clothes in the hamper, brushing teeth with help, helping set the table, feeding the dog with a parent nearby. Icons help, since the reading is still catching up. The win is that the chart exists at all, not that it is finished.
Three to five. More than that and a four-year-old quits looking at the chart. Pick the things you would already nag about, write them down, and let the chart do the nagging.
Stars are a unit, not a currency. Most families count stars on Sunday and trade them for a small reward — a movie pick, an extra story, a trip to the library. A few families pay cash for the bigger jobs and stars for the rest. Both work. Pick what your kid can hold in their head without a spreadsheet.
