Activity 1B: The Kinds of Teeth Extensions: Animal Teeth & Tooth Math

Give each student the worksheet "Kinds of Teeth."

  1. Read about the different kinds of teeth and their functions.
  2. Have the students record the kinds of teeth and how many of each are found in a person's mouth. Discuss with the students the position of each kind of tooth found in the mouth. You may want to mention that children have 20 "baby teeth." This activity looks at an adult mouth with its full complement of 32 teeth. Teens probably do not have all 32 permanent teeth; wisdom teeth usually penetrate the gums in the late teen years or in early adulthood.
  3. Now have the students look at the profile drawings below their charts and have them identify/label the kinds of teeth by color coding each tooth found.
    Incisors-red Cuspids-orange
    Bicuspids-blue   Molars-green
  4. From looking at the position of the teeth, have the students discuss the function of each kind of tooth found in the mouth.
  5. Have students observe the function of the different kinds of teeth in relation to different consistencies of food by participating in the Mechanics of Chewing Activity (1D). 

Extension Activities 

Animal Teeth:

The teacher can provide, or have students look for, pictures of analogous teeth in other animals. For example, incisors in dinosaurs, baboons, cats, rabbits, and molars in cattle, horses, and deer. 

Tooth Math:

Have students calculate fractions and percentages of each of the kinds of teeth in the mouth.
