With no plan, I still had a few activities that I came up with for the day when I don't want the kids to be in front of the tv, and they are starting to get bored.
So today....PAINTING RELAY!!!
Set up four stations, Set the timer for 5 minutes, and rotate through. (I also recommend starting 2 kids on #1 and #3, instead of #1 and #2 because if the 3 year old wants to linger, no one argues.)
