1. 1

    Show a photograph of a turtle with its head and legs out, then one with them pulled in. Ask: 'Where did the head go?'

  2. 2

    Say: 'The shell is part of the turtle's body. It grows with the turtle, and the turtle can never leave it.'

  3. 3

    Bring the turtle puzzle. Lift out and name the top shell, the head, the legs, and the tail.

  4. 4

    Show a photograph of the underside and name the bottom shell.

  5. 5

    Point to the plates on the shell and the claws on the feet.

  6. 6

    Give a three-period lesson on three parts at a time.

  7. 7

    Invite the child to work the puzzle, then match the three-part cards and check with the control cards.

What catches the child’s eye

  • The head and legs disappearing into the shell in the photographs
  • The pattern of plates across the top shell

Extensions, easiest to hardest

  1. Learn the words carapace (top shell), plastron (bottom shell), and scute (shell plate)
  2. Compare a sea turtle's flippers with a desert tortoise's thick, clawed legs
  3. Count the plates on the shell in a photograph
  4. Trace, color, and label a turtle booklet

Control of error

Each puzzle piece fits only in its own space; control cards show each part with its label.

Ready to move on when the child…

  • Names at least six parts of a turtle
  • Works the turtle puzzle without help
  • Says that the shell is part of the turtle's body

Guide note

Do not keep a live turtle in a classroom of young children: turtles often carry Salmonella, and health agencies advise against them for children under five. Use photographs, video, or a nature center visit. Desert tortoises are protected in Utah; never collect one.

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