This is my new birthday board. It is smaller, takes up less wall space in my room, and looks nicer than a poster with names on it.
Print out the months and number cards on card stock, laminate, and cut out.
The first week of school, group your students according to their birthday month. Give them the number card to hold and take a picture of them.
Print the picture and use sticky tack or another removable adhesive to put the picture on the month.
