The Number Rods  Introduction
 10 centimeters = 1 decimeter
 100 centimeters = 1 meter
MATERIAL:
 Ten wooden rods varying in length from 1 decimeter to 1
meter. Each decimeter is colored alternately red and
blue.
Thus, the first rod is entirely red, the second, which is two
decimeters long, is colored red and blue, and so on. These
rods
correspond in length to the red rods. A dark green floor
mat is
also needed.

PURPOSE:
 To learn to count to ten and understand the value of each
number. To learn the names "one" to "ten" and to associate
the
names with the quantities.
AGE:
 Four years and older
NOTE:
 Throughout the number work, the children must sit or stand so
that they see the numerals the right way up. It is counter
productive to
sit children opposite each other at a table when numbers or
letters are
being used or written. Each child sees the other child's
work
upside down. This can lead to reversal problems.

 When large numbers are being used, either with the golden bead
material or numerals, the children must always see these in the
correct
order  thousands, hundreds, tens, units, from left to right
(i.e.
3,247). This is because we read numbers from left to right
beginning with the largest.

 Special care must be taken in group exercises where the
children
stand. The teacher can be on the wrong side of the work,
but the
children must stay on the side to see the work right side up and
should
not come to stand beside her. Any children who wander over
to
watch must stand in front of the work even if they have not yet
reached
the stage of the exercise that the others are doing.
