Cards and Counters is a material that consists of 10 number cards, 1-10, and 55 round, red counters, each approximately the size of a nickel. This work is typically organized on a floor mat in the Montessori classroom, as it requires a bit of space.
It brings the abstract to the concrete, allowing a child to feel the units as they count. Not only does it appeal to a child’s natural sense of order, it’s also very visually appealing.
