P or P
(Parallel or Perpendicular)
u Materials:
• Equation cards
• Relationship cards
• Paper
• Pencil
• Equation sheet
• Timer
u Directions:
Students play in two large groups.
1. Divide the students into two teams. Each team needs one set of equation cards, one set of
relationship cards, and one equation sheet.
2. One student from each team gives one equation card to each team member and flips over
a relationship card.
3. On the count of three, the timer begins, and students turn over their cards. Students work
as a group to find pairs of equations with the relationship stated on the relationship card.
4. For one minute, students record as many pairs of equations as possible on the equation
sheet.
5. After each round, the cards in each stack are collected and shuffled, and a new round
begins.
6. Each correct pair is worth one point.
u Who Wins?
The team with the highest number of points wins.
u Tip:
The timer should be large and visible for all students.
