Montessori Activities - Sorting

Sorting is a fundamental activity in the Montessori environment that helps children develop logical thinking and discrimination skills. The activity involves arranging objects according to a certain criteria, such as colour, size, or shape.

Importance of sorting:

Sorting provides children with opportunities to develop their cognitive abilities and fine motor skills while having fun. Children learn to differentiate and classify objects based on specific criteria, which is essential for developing problem-solving skills and understanding mathematical concepts.

How sorting works in the Montessori environment

The process of sorting begins with a selection of objects that children can use to sort. These objects can be anything from beads and buttons to shapes and letters. Once the objects have been selected, children can then begin to sort them according to a specific criterion. For example, children may be asked to sort objects by colour, shape or size.

Benefits of the sorting exercise:

  • Helps develop a child's cognitive skills, especially their ability to categorise and organise information
  • Encourages fine motor skills, as they manipulate the objects
  • Provides a sense of order and structure
  • Enhances vocabulary and language skills
  • Allows the child to work independently and build self-confidence

Montessori approach to sorting

The Montessori approach to sorting involves allowing children to work at their own pace and giving them the freedom to explore their own ideas. The materials used for sorting are carefully selected to provide children with the appropriate level of challenge, ensuring that they are neither too easy nor too difficult.

Materials needed for sorting

  • A large empty oatmeal container cylinder
  • Five each of two different objects such as blocks and balls
  • Two bowls
  • Tray
  • Mat for floor work

How to set up and present the sorting exercise:

  1. Invite your child to join you for this exercise.
  2. Unroll the mat and bring the tray to the mat.
  3. Take the lid off the container and put it to the side.
  4. Put two bowls on the mat.
  5. Take out a block, say "This is a block," and place it in the left bowl.
  6. Take out a ball, say "This is a ball," and place it in the right bowl.
  7. Sort all the objects.
  8. Mix them up again by putting them back into the container.
  9. Let your child sort them.
  10. You and your child can share the cleanup or let your child do it alone.

How to expand the sorting exercise:

  • Take a large empty oatmeal container cylinder and wrap it in construction paper.
  • Fill it with five each of three different objects such as balls, small empty containers, blocks, or movable alphabet letters.
  • Sit with your child on the floor mat.
  • Follow the same procedure we always use for this type of presentation.
  • Let your child repeat the process if they want to.

Points to note:

  • Use identical objects within a set for sorting
  • Work from left to right or let your child work in any order they prefer
  • Do not rush the process, allow the child to take their time
  • Always supervise children during the exercise


Overall, sorting is an essential activity in the Montessori environment that helps children develop logical thinking and discrimination skills. It is a fun and engaging way to enhance cognitive abilities and fine motor skills while providing children with the opportunity to explore their own ideas and work at their own pace. By engaging in sorting activities, children develop important skills that will serve them well in their future academic and personal pursuits.
