The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. Remember that they are not the same thing - the reference angle is the angle between the terminal side of the angle and the x-axis, and it's always in the range of [0, 90] (or [0, π/2]).
4.1 Degrees and radians Introduction Angles can be measured in units of either degrees or radians. This leaflet explains these units and shows how it is possible to convert between them. 1. Degrees and radians Angles can be measured in units of either degrees or radians. The symbol for degree is . Usually no symbol is used to denote radians.

The problem with this is for example, when the time is 11:50, it looks like it's almost 11 o'clock, when the truth is, it's almost 12 o'clock. This can be improved by calculating the angle for the hour hand by including the fraction of the hour.

O ne day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up.
The minute hand angle is the easiest since an hour (i.e. 60 minutes) corresponds to the entire 360 degrees, each minute must correspond to 6 degrees. But unless the time is EXACTLY something o'clock, you have to write the time as a fractional number of hours rather than as hours and minutes.
In Year 4, children need to convert between units of time (hour and minutes). They need to read, write and convert time between analogue and digital 12-hour and 24-hour clocks.
