Rods are a collection of rectangular rods of 10 lengths and 10
colors, each color corresponding to a dierent length. The smallest rod, a white
centimeter cube, is 1-centimeter long; the longest, the orange, is 10 centimeters.
Cuisenaire

Rods provide a continuous number model, rather than a discrete one.
Thus they allow you to assign a value to one rod, and then to determine the values
of the remaining 9 rods by using the relationships between the rods. For example,
when the white rod is given a value of 1, the orange rod, which is ten times as long,
has a value of 10; if the white rod is given a value of 2, the orange rod is 20; if the
orange rod is 1, the white rod is 1/10.
Activities with Cuisenaire
®
Rods are appropriate for grades K through 8. They help
students to explore whole numbers, fractions, measurement, ratio, area, perimeter,
symmetry, congruence, three-dimensional geometry, patterns,and functions.
Free exploration
Give students time to play with the rods before using them in directed lessons.
Students are likely to make designs, create pictures, and build three-dimensionally.
They will begin to notice rod attributes and relationships, for instance, that all blue
rods are the same size, two reds equal a purple, or a purple is one white rod less
than the yellow.
Provide guided exploration by asking students to lay one rod of each color flat on
their desks to make a staircase. Have them discuss in their small groups what they
notice and then report back to the class. Consecutive rods, for example, dier by
the length of one white rod. Students often prove this by placing a white rod at the
end of each rod (except the orange) in the staircase [Fig.1].
