Coins with time intervals
thingiverse
We've used small coins or tokens with our kids as rewards for "screen time". Whenever they do something good, they get these coins that can be traded in to play some video games. We offer three options: 15-minute, 30-minute, and 60-minute coins. This system has worked well for us!
