Teaching guide

What students learn

Solve problems about how long things take, including situations with am and pm and converting between units of time.

How to teach it

Count on from the start time to the next hour, then add the remaining minutes, using a number line of times. Bridge over the hour carefully.

Worked example

Generated and checked in code, so it is correct.

Watch out for

Subtracting times like plain numbers (treating 60 minutes as 100) and losing track when crossing the hour.
