The Number Rods - Exercise 2
- The teacher takes the one, two, and three rods to the floor mat
with the child and proceeds to teach the names, using the three period
lesson.
Period 1
- The teacher keeps the rods to one side. She places the one
rod in front of the child and names it several times. "One...one...this
is one."
- She takes away the one rod and places the two rod in front of the
child. She names it several times. "Two...two...this is
two." She then counts the segments once, "One, two," touching the
center of each segment with her forefinger as she does so, being
careful not to hide the rod with her hand. Touching the second
segment, the teacher again says, "Two...two...this is two."
- The teacher puts the two rod to one side and places the three rod
in front of the child. She names it several times.
"Three...three...this is three." She then counts the segments,
"One...two...three."

Period 2
- The teacher puts the three rods in front of the child in mixed
order. Each rod is parallel to the others and the rods are a
short distance apart. The teacher names the rods in turn, and the
child indicates that he knows the correct rod by pointing to it or by
giving it to her. If he is successful, he has made the
association between the name and the quantity.
Period 3
- The teacher puts the rods to one side. She places a rod in
front of the child and asks him to name it. For example, she
places the three rod in front of him and asks, "How much is
this?" If he says "Three," then she asks him to count it.
He counts the segments, "One, two, three." This is repeated
several times with each of the rods.
Summary
- The teacher arranges the rods in sequence with red ends even on
the left. She counts the rods, "One...two...three."
On subsequent days, one or more rods are added to those already
learned,
until the child can count all the rods. The material is kept on a
shelf
and the child takes it out as often as he likes. He counts the
rods and
arranges them in their correct sequence from one to ten.
