1. Put samples of the different
mollusks on a table for the
children to see and touch.
Cut out the shapes of the
mollusks for which you lack
examples (e.g., octopus,
squid, sea slug). Discuss the
different types and show the
children pictures of mollusks
from books and magazines.
2. Have the class complete the
worksheets : Snails ; Clams,
Cockles, Mussels, and Scallops;
Mollusk Count : Mollusk
Math; Octopus Cutout; and
Mystery Mollusk. (Mollusk
Math was contributed by Kathy
Amerman , Maureen Coon.
Kathy Dill, Mae Dunsing, and
Larry Trani, Baranof Elementary,
Sitka.)

Make mollusk matching puzzles.
Divide students into groups of
two or three and give each
group a piece of butcher
paper; crayons, pencils or
felt-tip markers; masking tape
and 15 different mollusks-cardboard
cutouts or shells.
Have students trace the mollusk
shapes and write arithmetic
problems (e.g. 3+4, 5-2)
on the butcher paper. Then
have them write the answers
on masking tape and stick
these to the undersides of the
mollusk cutouts. After the
members of each group are
finished, have them exchange
their puzzle with another
group--and see how fast they
can match the tracings with
the shells or cutouts. They
can check their answers by
doing the math problems!
Additional activities:
1. Math, Science : Have students
measure their shells and
cutouts and make bar graphs
using these measurements.
2. Science, Language Arts :
Bring live univalves or bivalves
into the classroom for a
brief showing. Have the class
write a story about how fast
they move, how they bury
themselves, how they feed.
Keep the animals cold (in the
refrigerator) and take them
back to their beach habitat as
soon as possible, so that they
can continue to fascinate
future beach visitors.
