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.
