Safety

  • Check laminated cards for peeling edges and sharp corners; loose laminate film is a choking hazard.

Presentation

  1. 1

    Bring the box to the table. Place the two header cards side by side at the top of the mat and name the groups: "These are animals. These are vehicles."

  2. 2

    Name each card as you place the mixed cards in a pile.

  3. 3

    Take the top card, name it, and say its group: "Horse. A horse is an animal." Place it under the animal header card.

  4. 4

    Take the next card and do the same for the other group.

  5. 5

    Hand the child the next card and name it.

  6. 6

    Wait while the child decides. This is the point of interest: the child chooses the group and places the card.

  7. 7

    When all cards are sorted, name the cards in each group. Put them back in the box.

Extensions, easiest to hardest

  1. Groups that are closer together: animals that live on a farm and animals that live in water
  2. Sorting real objects or replicas into the same two groups
  3. Three groups
  4. The child turns the cards over and checks the color dots

Control of error

The adult at first. The matching color dot on the back of each card and its header card lets the child turn the cards over and check.

Ready to move on when the child…

  • Sorts 8–10 cards into two groups without help
  • Says the group name for a card ("animal")
  • Sorts real objects into the same two groups
  • Takes out and returns the work on their own

Guide note

Avoid groups with unclear borders for toddlers, such as fruits and vegetables (a tomato is both, depending on who is asked).

Try “pink tower”, “tummy”, “diaper”, “grace and courtesy”, or “October”.
