If you have a beach classroom theme, these adorable birthday beach sandcastle posters are just what your classroom needs! There is a colorful sandcastle poster for each month. Each sandcastle has three flags for student names/birthdates. Please note that the flags are on the small size. I also included a colorful beach clip art image on each poster if you have more than three students with a birthday in that month. In addition, I included three pages of beach clipart images for student names and birthdates if you need to add more students in a particular month. I highly suggest laminating these posters and using a dry erase marker to write your student names and dates on. That way you can use these adorable posters year after year.
