Refraction Game Teaching Strategies

  • The Refraction game teaches fractions by adopting three models: laser width (continuous), flow frequency (discrete), and lasers colored by denominator.

  • In later stages of the game, students can design their own levels for their peers to play. You may want to provide additional class time for students to demonstrate their learning in this way. Challenge students to create levels that require their peers to practice and apply various fractional concepts.

  • If students have difficulty figuring out the game or explaining their strategies, you can show the first two minutes of the demo presentation to stimulate their thinking and facilitate the discussion.

  • After 10-15 minutes of game play, talk with students about their strategies. Ask questions such as, What determines the color of the laser? What happens when you try to power a spaceship with the wrong piece? How can a two splitter be used to make sure each ship has the right amount of power?
