We have a new chores system, well, more of an addendum.
In addition to their regular chart of chores--including feeding the cats, taking out the garbage, unloading the dishwasher, rotated by odd or even dates--for which they are unpaid because we see it as part of their family responsibility, they can now pick up "jobs for hire," which I'll post on sticky notes. These vary week to week, season to season--shovel snow, water the garden, take out the recycling, fold the clothes, whatever I can come up with--and are paid in tickets. These tickets are redeemable for screen time OR for cash equalling about $2.50 to purchase books, toys, souvenirs, music, whatever. Which means we're also going to start having them pay for more things (though, no doubt we'll still purchase or go halves on things.) There can also be surprise reward tickets; also, we won't be taking any tickets away as punishment (though, we can delay the use of screentime as a consequence.)
They are so excited! Bud earned six tickets just yesterday, for taking out the recycling and folding and distributing 5 loads of laundry. This morning, he and Sis unloaded the dishwasher TOGETHER, working as a TEAM, for which I gave them a surprise ticket each. Sis is planning to water the garden soon and regularly. Plus all those tickets they got for the cursing at the Memorial Day party!
We'll see how it all goes, but it seems promising.
