Tooth by Tooth: Comparing Fangs, Tusks, and Chompers


Tooth by Tooth: Comparing Fangs, Tusks, and Chompers
Written by Sara Levine, Illustrated by T.S. Spookytooth

Publisher’s Summary:
What animal would you be if a few of your teeth grew so long that they stuck out of your mouth even when it was closed? What would you be if your top canine teeth grew almost all the way down to your feet? This picture book will keep you guessing as you read about how human teeth are like–and unlike–those of other animals.

Primary Source Pairing:
Open wide and take a close look at animal teeth in this fun and informative book. To deepen the understanding of the animals presented in this book, invite students to study photographs of the animals and compare the photographs and the illustrations. Print the photo collage above or create a station rotation activity with a different animal’s photograph at each station and instruct students to make observations as they rotate through the stations.

Questions for Discussion:

  • Look at the teeth of the animals.
  • Describe what you see.
  • What is surprising to you?
  • What do you see that you didn’t expect?
  • What do you see that you cannot explain?
  • Look in the book and find an illustration of a child with animal teeth. Next, look at the photograph of that animal and focus on its mouth and teeth.
  • What do you notice about the illustration that shows the way the animal’s teeth look in the photograph?
  • What is interesting to you when comparing the illustration to the photograph?
  • What questions do this analysis and comparison create for you?
