Cards and Counters


This week, I’m sharing a Montessori Math Material called Cards and Counters.  This work can be made by anyone, with little or no cost.  The material is used for practicing counting with one-to-one correspondence and learning the concept of odd and even numbers.

All you’ll need:

  • Cards, labeled from 1-10 (mine, pictured here, are just typed numbers I laminated)
  • 45 identical objects (Objects that are different, paired with numerals is called the Sets Basket, which involves sorting and counting.  Cards and Counters is simply for counting)

To present the lesson:

  • Show the work, tell the child the name of the work
  • Help the child lay out the cards in order
  • Take one at a time for each numeral card, laying them in pairs.
  • If there isn’t enough to complete 10, there would be a mistake.  This is known as built in Control of Error.
  • Show the child how to run his finger between the paired counters, the counters who do not have a pair are known as odd.  The numbers that have all pairs is called even.


Sometimes, I like to change the counters for seasonal fun to add interest.  This month at home, I have little orange leaves.


What will you count?
