For example
At 10 o'clock the clock hands make a reflex angle the long way round.
In Grade 5
Children mark the outside of an angle to see the reflex angle that most people miss.
Watch out for
Children often measure the smaller angle when the reflex one was asked for. The two together make one full turn.
Say it at home
Point at a clock and talk about the bigger way round between the two hands.
