When students lose a tooth, have them add their name to a lost tooth graph. Graphs may take the forms of pictographs where students write their names on a tooth-shaped cutout and place the cutout above the correct month. Students also may create bar graphs where they color in a square above the correct month to show when a tooth was lost. Study the graphs to see which month has the most lost teeth or if anyone lost two or more teeth in a single month.
Read stories about lost teeth and the tooth fairy such as "What Do the Fairies Do With All Those Teeth" by Michel Luppens, "Dear Tooth Fairy" by Alan Durant or "The Real Tooth Fairy" by Marilyn Kaye. Ask students where they think their lost teeth go when the tooth fairy collects them. Have student write and illustrate real or imaginary stories about losing teeth or the tooth fairy. Hang stories and drawings on a "Where Do Lost Teeth Go?" bulletin board.
Photocopy, laminate and cut out images of the typical set of 20 baby teeth. Tape the baby teeth all around a bulletin board in no particular order. Next to the board, hang a diagram of a set of baby teeth in their proper location. Invite students to arrange the baby teeth in the correct order. For older students who can read, encourage them to place labels near the teeth to identify incisors, canines and molar teeth.
Invite students to learn about the teeth of various animals. Place laminated pictures of a human child and other animals, such as a kitten, shark, snake, beaver, hippo, cow or horse, on a bulletin board. Laminate pictures of teeth to match each animal. Invite students to match the teeth to the correct animal by taping the laminated tooth below the correct animal. Discuss which clues students used to match the teeth to the animals.
