I created a custom calendar for my classroom, and since I have thirty students this year, each one of them gets to be a calendar day!
The calendar is made of thick poster paper with clear plastic stapled to make sleeves. The photos are square-cropped and laminated.
I created little icons — for birthdays, holidays, special days, and test days — that can be sticky-tacked right above the photos when appropriate.
I made the 31st day my picture, by the way.
This is really cute, I can have my kids do double duty on the dates.
