What are Number Rods?

The Number Rods expose students to the concept of measurement. Instead of looking at two rods and saying, “this one is longer,” now the student is able to actually quantify exactly how much longer. While this might seem like a rather intuitive skill, it actually takes a fair bit of practice to be able to judge and compare quantities. The Number Rods are introduced to students of about four years of age, once the student has mastered the Red Rods and has expressed interest in the Number Rods.

A set of Number Rods consists of ten colored rods, divided into equally-sized red and blue sections. The length of the rods progresses linearly, with the second rod being twice the length of the first, the third rod three times the length of the first, etc.

 

Purpose:
Working with the Number Rods teaches children to quantify measurement. Instead of noticing that 10 is longer than 1, the child can see that 10 is precisely ten times longer. They learn to ask not just “is it longer?” but, “How much longer is it?”

The Number Rods also help children learn the names of numbers and their sequence and learn to correctly associate between the spoken number and its quantity. Children grow to understand that each rod represents a unique quantity and that each number is represented by a single object as a whole, separate from others. Later on, students work with another material, the Number Rods and Cards, which link the symbol for a number to the physical quantity.
