If you want to celebrate the birthdays of your preschool class, make a bulletin board that includes everyone at once. For each child, make a shape that coincides with the month of their birth. Choose shapes that are easily recognizable for small children: a Christmas tree for December, a maple leaf for fall months or a flower for the spring. If you have been teaching basic shapes, you can incorporate them into the board as well. Cut each shape out of brightly-colored construction paper and write each child's name and birthday; kids can take their shape home at the end of class.
To help toddlers get acquainted with the concept of calendars, make a bulletin board that plots out the birthdays for each month. Use a bright, colorful background and make the calendar overlay by using markers or strips of colored electrical tape. On each birthday, place a photo of the child in the appropriate square; this allows small children to recognize the child when they cannot read yet. The bulletin board can be used as a learning tool for the days of the week, numbers, dates, or months.
When your toddlers are learning their colors, you can make a bulletin board that acts as a visual aid and celebrates your students. Get a bunch of solid-colored, flat helium balloons and arrange them on the board so they look like a bouquet of balloons; add ribbon strings to the bottom and gather them into a bunch. On each balloon, write the name and birthday of one student, using photos to help kids match names and faces. Toddlers will enjoy the three-dimensional nature of the boards and can point to the balloons in the colors they recognize.
Design a birthday bulletin board that features an individual student to help the class get to know each other. Make a background that includes a space for a student's picture and a slot for their name, age and favorite things. Cut various shapes out of construction paper to serve as representations of the things toddlers might like: toys, certain foods, family or pets, for example. When a new birthday rolls around, put up the student's name, photo and age, and have them pick out their favorite things to put up on the board.
