Hang this tooth graphing poster near your calendar time and graph who has lost a tooth each day.

Allow the student who has lost the tooth to follow the pattern and color in their tooth.

Keep tally marks on the bottom of each month to record/teach another math counting system.

I chose colors appropriate or symbolic to the month. For example, Christmas red and green in an ABAB pattern for December, Halloween's black and orange for October, and one you might not have guessed for September's ABC pattern of red-yellow-green represented the colors of apples, which we study during that month.
