Another "eggsperiment"---soak a hardboiled egg in vinegar for 3-5
days. The vinegar will eat away the eggshell, just as acidic foods
eat away the enamel on our teeth if we don't brush. |

This
is a dice toss game. The child gets six marshmallows, a mouth
workmat, and a graph recording sheet like the one on the right. The
child tosses a die, counts out the marshmallow "teeth" on to the
mouth, and then records the toss by coloring in a block on the
graph. He is finished when he reaches the top of one column and
records the number of tosses at the bottom. |

Give
students a mouth model and have them count out 20 primary teeth
(mini marshmallows). If it's later in the year, they can count out
32 adult teeth.

The
caption on the left were the instructions for this locker
decoration. I photographed each child's mouth, taped a picture of
the child to the locker and then taped the mouth photo over the
picture. We also made this into a "Who Is Smiling?" class book. |
