Number Rods, Extension Cards, Ages 4-6

Let’s talk about the power of Montessori’s Number Rods with Extension Cards! The Montessori Number Rods are a foundational Montessori material used to introduce children to the basic concepts of math such as counting, number sequencing, and size discrimination. These rods come in varying lengths and colors, each representing a different numerical value. The direct aim of using the Number Rods is to teach children to isolate numbers and comprehend their relative value in a visual, tactile manner. The indirect aim of this work is to develop their concentration, focus, and fine motor skills.
