The Number Rods - Introduction
- 10 centimeters = 1 decimeter
- 100 centimeters = 1 meter
- 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
- 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.
- Four years and older
- Throughout the number work, the children must sit or stand so
that they see the numerals the right way up. It is a bad habit 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.
