Give
each child a 2.5 cm (1") square
construction paper template frame.
Ask
everyone to place the square randomly on a well grassed area about 3m
by 3m (10' x 10').
Each
child counts the number of blades
in his or her square.
The
sum of the blades in all the samples is found and averaged.
This
figure provides a base for calculating the size that an area would have
to be to contain a million blades of grass.
This
is a great problem to donate to a
willing eighth grade class to solve.
Encourage
children to visualize a hot
dog replacing each tiny blade of grass.
Then
introduce the word "googol" and note that this term represents all the
units that would be contained in a million stakedout plots.
Challenge
them to express "googol" in
numerals (a 1 followed by 100 zeros).
PS: Consider doing more fun printable
math activities.
