What a wonderful & bright way to start students' & your day!
Simply decide on a design and print. I choose to buy a cheap frame from the Dollar Store to display in my classroom. Each day I begin with writing (using a dry erase marker) with why today is wonderful. Maybe there is an assembly or it it someone's birthday! If nothing too special is happening, I write a fun fact, such as "Today is wonderful because... it is national french fry day!" or something of the sort.
Another option is to print and laminate and then hang somewhere in the room.
Feedback is appreciated.
