Purpose: For students to develop an understanding
of the correspondence between numbers and actual quantities.
Materials: Handmade, or purchased, cut-outs of
ghosts; about 400 mini-marshmallows (or enough for each student, or
group, to have about 20); 20 sandwich bags, or enough for each student;
10-sided dice, enough for each student, or group, to have 1; a bell
or noise-making device.
Procedure:
Read "A
Creepy Countdown" to the class.
Have
a brief talk about the characters/creatures in the book and, if
possible, lead the discussion around to pets.sExplain
to the class that they're all going to have a really neat pet today,sa
ghost! (You could also pretend to enlist the
class's help with feeding the teacher's
pet ghosts).
Pass out
ghost cut-outs to students.
Pass out
a bag of marshmallows to each student (each bag should contain about
20 marshmallows). Be sure to stress that marshmallows are lnot
to be eaten until snack time!
Pass
out one 10-sided die to each student.
Explain
to students that this is feeding time for the ghosts and they only eat
marshmallows. Whenever the teacher rings the bell, students roll the
10-sided die and place the corresponding
number of marshmallows onto the cut-out
of the ghost.

If
students grow bored with
activity, a more difficult addition is to let
lthem yell out "Boo to you!" whenever
the number of marshmallows on
the ghost equals 10.
An
additional variation, with possibilities for addition and subtraction
development,lis
to start the ghost with 20 marshmallows already on
it and take away the number
of marshmallows rolled. Once they get
to zero, or must take away more
than what's available, they could get to shout "Boo to you!".
Oflcourse, they would get to eat the lmarshmallows
as they subtract them!
