Common mistakes

What learners typically get wrong, and how to fix it.

  • Treats 1:50 + 20 min as 1:70.

    Correction: 60 minutes make an hour: 1:70 is 2:10.

  • Uses a calculator and gets decimal hours.

    Correction: Count on in hours, then minutes, on a timeline.

Teacher tips

  • · Use a number line split into hours for durations.

Parent tips

  • · Ask how long until dinner from the current time.

Real-life applications

  • · Reading timetables, planning a day out.
