  • Ask students to give you a thumbs up if they have ever done a puzzle. Show a few examples of different puzzles.
  • Tell students that today they will be using pieces from a special type of puzzle called a tangram. Define tangram as an ancient Chinese puzzle that uses shapes to create different pictures. Explain that "ancient" means that these puzzles are very old, and were created a long, long time ago. Display the tangram Vocabulary Card.
  • Instruct students to turn and talk to a partner to name as many different shapes as they can. Tell students that some of those shapes are part of a tangram puzzle.
  • Tell students that today they will practice being "shape detectives" who search for shapes hidden within other shapes.
