This game offers you an opportunity to improve your ability to estimate angles.
You can either play on your own or challenge a friend.
The closer you get to the target angle the more points you will score.
There are four levels:
Level $1: 0-90^\circ$
Level $2: 0-180^\circ$
Level $3: 0-270^\circ$
Level $4: 0-360^\circ$

This investigation explores using different shapes as the hands of the clock. What things occur as the the hands move.
On a clock the three hands - the second, minute and hour hands - are on the same axis. How often in a 24 hour day will the second hand be parallel to either of the two other hands?
During the third hour after midnight the hands on a clock point in the same direction (so one hand is over the top of the other). At what time, to the nearest second, does this happen?
