One calendar contains little doors for each day. I put a note in each door that tells the boys what activity we'll be doing that day. Our other calendar is the Playmobil lego-like type. Each day they open a box of lego-like pieces to create an entire scene by the end of the month.
Dec 1 - Eat dinner at Chick-fil-a and enjoy their Christmas lights and snow
Thanks for the pics Kelly!
