Quick check

If the learner watches the second hand go all the way round a clock, can they count that as one minute — and estimate roughly how many minutes their favourite TV show lasts?

What mastery looks like

What a learner can do once this topic is secure.
  • Use a sand timer or stopwatch to time an activity
  • Begin to understand that 1 minute = 60 seconds
  • Record a duration in simple terms (e.g. 'it took about 2 minutes')

Teaching notes

From the Marble Skill Taxonomy. These notes have not been validated in classrooms, so treat them as a starting point for your own judgement.

The approach

Young children (around ages 5-6) learn to MEASURE elapsed time using tools — sand timers, stopwatches, counting seconds — to time real activities and record results in simple units ('about 2 minutes'). The core skill is procedural and embodied: start the tool exactly as the event begins, stop it exactly as it ends, then read off the duration. The conceptual underpinnings are that duration is how long something lasts from start to finish, measured with a tool rather than judged by how fast, effortful or busy the activity felt, and that 1 minute = 60 seconds, which is a genuine conceptual step because 60 is not a base-ten grouping.

Common misconceptions

  • Judges duration by speed or by how much happened, not elapsed time (carried from comparing durations)
  • Starts or stops the tool out of step with the event
  • Reads the number currently showing as the duration, ignoring where timing started
  • Thinks 'a minute' and '60 seconds' are different amounts

Useful representations

  • Sand timers of known durations (1 minute, 3 minutes)
  • A stopwatch or large seconds display
  • A number line / counting track of seconds
  • A one-minute timer paired with a count to 60

Teaching practices

  • Time real, meaningful activities (how long to write your name, to tidy up) with a visible tool
  • Model starting and stopping the tool exactly AT the start and end of the event
  • Use sand timers first — duration is visible as the sand falls — before digital stopwatches
  • Introduce 1 minute = 60 seconds by counting seconds until a one-minute sand timer empties
  • Record informally ('about 2 minutes', 'a bit more than a minute') rather than demanding precision

Activities to try

  1. 1

    Time a real activity with start and stop aligned to the event

    Why it works: 'How long' is a quantity you can capture with a tool by aligning start and stop with the event, not a feeling guessed from how fast or how effortful the activity was.

    1. Pick a short, real activity to time (e.g. writing your name five times, tidying a small tray, building a block tower).
    2. Choose the right tool: for an open-ended duration use a stopwatch or a seconds count/large seconds display; a fixed one-minute sand timer is best for checking whether something takes about a minute or comparing against its known span.
    3. Hold the visible timing tool ready.
    4. Count '3-2-1 start' and start the tool at the exact moment the activity begins.
    5. Stop the tool the instant the activity finishes (on the last action).
  2. 2

    Build 1 minute = 60 seconds by counting a one-minute timer

    Why it works: A minute and 60 seconds are the same amount of time, not two different amounts — the 60-grouping is something you can experience by counting it out.

    1. Turn over a one-minute sand timer and count the seconds aloud (or follow a seconds display) until the sand runs out.
    2. Notice that the count reaches about 60 as the minute ends, provided each number is paced to one second (e.g. by following a seconds display); young children counting freely often go faster and reach a higher number.
    3. Say the relationship: 'one minute is the same as 60 seconds.'
    4. Check with a second tool: 'If we used the stopwatch instead, would it agree?'
  3. 3

    Compare two durations and read a growing span, not the end number

    Why it works: Duration is the amount of time that elapsed between start and stop — represented as a length that grows from the start — not simply the number currently displayed.

    1. Time two different activities and record each duration ('about 20 seconds', 'about a minute').
    2. Represent each duration as a length — e.g. a bar that grows FROM the start, or line up the two timings side by side.
    3. Decide which activity took longer by comparing the lengths.
    4. If using a stopwatch, note or zero the start first, so the duration is the span covered, not whichever number happens to show at the end.
