Tooth Diagram
Discuss:  We used the diagram on page 3 of the Parts of a Tooth Speedy Science download.  I also found a good diagram on page 23 of The Best of THE MAILBOX Theme Series: Dental Health (Grs. K-1) that I used.

Enamel - A hard substance the covers the tooth and lies over the dentin.
Root- The part of the tooth that holds the tooth to the bone

Dentin - A yellow substance, harder than bone, that makes up most of the tooth.

Materials:
  • Construction Paper
  • Glue
  • Pen
  • Scissors
Directions:
  1. Cut a tooth outline from white paper. Or use the pattern on page 15 of  The Best of THE MAILBOX Theme Series: Dental Health (Grs. K-1)
  2. Cut out a pink tooth outline a bit smaller than the white one.
  3. Cut out a red piece even smaller than the pink one.
  4. Label the top of the white “enamel” and the bottom “root”
  5. Label the pink “dentin” and the red “pulp”.

Number Crunching
I found a free Number Crunching subtraction worksheet. We used it to review barrowing to solve subtraction problems.

Set of Teeth Game
I found this Set of Teeth Game that we played with mini marshmallows.  We rolled the dice and added that many marshmallows to our set of teeth.
  
Edible Teeth
Materials:
  • Apple slices
  • Mini marshmallows (we used the mini marshmallows from the activity above so the boys didn't have too many sugary foods while I was trying to teach them about taking care of our teeth)
  • Peanut butter
Directions:
  1. Spread peanut butter on an apple slice and stick mini marshmallows to it.
  2. Add another apple slice with peanut butter to the top of the marshmallows.
