Practice with Rotations

• Divide the class into two teams, named “X” and “O”.

• Draw a large tic-tac-toe grid on the board.• Take turns asking questions of each team. The

answer must include an explanation.– If answered correctly, they

may place their symbol on

the game board.– If answered incorrectly, the

other team may place their

symbol on the game board.

• The first team with 3 symbols

in a row wins the game.

Question 2

• FALSE• The number of degrees separating the center

lines of the blades on this fan is 60°.

• WHY? There are four blades on the fan. Divide 360° by 4. The blades are 90° apart.

Question 5

• TRUE or FALSE?• Fish 2 is a 45° counterclockwise rotation of Fish 1.

• WHY?

Page 12: Practice with Rotations Tic-Tac-Toe Questions. Practice with Rotations Divide the class into two teams, named “X” and “O”. Draw a large tic-tac-toe grid.

Question 5

• TRUE• Fish 2 is a 45° counterclockwise rotation of Fish 1.

• WHY? Remember 45° is half of a 90° rotation.

Question 6

• TRUE or FALSE?• Polygon A'B'C'D' is a 180 degree

counterclockwise rotation of polygon ABCD.

• WHY?

Question 6

• TRUE• Polygon A'B'C'D' is a 180 degree

counterclockwise rotation of polygon ABCD.

• WHY? Remember the letters which label the diagram do not have to be rotated.
