Have students practice finding complementary and supplementary angles while they play Rolling C & S!
This is a two player game and students will need playing pieces (my students usually used two-sided red and yellow chips) and one die.
Students roll the die and move forward that many spaces. If they rolled an even number they find the complement of the space they landed on. So if they rolled a 4, they would have landed on 78 degrees. So they would find the complement of 78 degrees.
However, if they had rolled a 5, they would have landed on 41 degrees and since 5 was odd, they would have found the supplement to 41 degrees. As Now, if their partner can prove that they made a mistake, they must go back to start! This means that both players are doing the math each and every time.
