Time

Akopọ

Telling and calculating with time is a skill we use every day, yet it trips people up because time is not based on tens: there are 60 seconds in a minute and 60 minutes in an hour. Reading timetables and working out durations correctly is a small skill that prevents big mistakes.

In this lesson you will calculate with units of time, switch between the 12-hour and 24-hour clock, and read clocks and timetables to work out durations and arrival times.

Awọn Afojusun

  1. Calculate with time: seconds (s), minutes (min), hours (h), days, weeks, months, years, including the relationship between units.
  2. Calculate times in terms of the 24-hour and 12-hour clock.
  3. Read clocks and timetables.

Akọ̀wé Ẹ̀kọ́

Time questions test careful reasoning rather than hard arithmetic. The trap is treating time as if it were decimal, so a clear method for durations and clock conversions protects easy marks.
