II.ProblemSolvingActivity-TransformationGame



  • In this game, students are going to manipulate one figure to represent the clues that the team has been
    given. You can play this as a whole class and make it about the speed with which a team can complete
    the transformation.

  • Each team will need a triangle (made of cardstock) and a large coordinate grid. You can do this on chart paper.

  • Each team starts with their triangle in the first quadrant. The team can decide where to put it. They draw it in
    or trace it in as the starting point.

  • Now the team has a moveable triangle and a drawn one.

  • Then call out the first command, “Rotate 90◦[U+0080][U+009D]

  • The team rotates the triangle using the moveable triangle and places the triangle in a new place to show the
    rotation. When the team has completed the task they raise their hands.

  • Teams that are correct and finish first get a point.

  • Then begin again. The team moves the triangle back to the starting point and starts again. Call out a new
    command.

  • Example “Translate 5 right and 3 down.”

  • Then the game repeats.


III.MeetingObjectives



  • Students will identify and use congruence transformations.

  • Students will identify coordinate notation for translations.

  • Students will identify coordinate notation for reflections.

  • Students will identify coordinate notation for rotations.

  • Students will practice all of these in a creative game.


IV.NotesonAssessment



  • Assessment is completed through observation as each team is playing the game.

  • Make note of teams that are having difficulty and offer assistance after class.

  • If necessary, stop the game and offer corrections or review.
