Math Problem of the Week - Lower Elementary - Aug. 15, 2021 to Aug. 21, 2021

Lower Elementary: 

Question: Jack is sitting in a swivel chair facing north. He spins a half turn clockwise, then a quarter turn counterclockwise, then a full turn clockwise, and finally a three-quarter turn counterclockwise. In which direction is Jack facing now?

Answer: Jack is facing south.

Solution: If Jack starts facing north and spins a half turn clockwise, he will face south. Then, a quarter turn counterclockwise will cause him to face east. Next, a full turn (in either direction) will cause him to face east again. Finally, a three-quarter turn counterclockwise will cause him to face south.
