Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Measuring and recording durations means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Ruler, cup, or clock as fits the topic; Paper for recording. Adult measures one example and records the unit. Child makes three measurements or time/money readings and records each with units. Done: three recordings with correct units. Stop after the fresh check; keep optional challenge for another day.

Before you open · source notes
Elapsed-time story problems ask how long homework takes using clocks. This is duration practice, not every calendar skill.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk what time the work started and ended, then how many minutes passed. One story does not prove every clock-reading skill.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-11 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- 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')
- Estimate whether brushing teeth takes about 2 seconds, 2 minutes or 2 hours, then use a supplied suitable timer to measure the event and record its duration
“Given a suitable timer, can your child estimate the duration of a short everyday activity in an appropriate unit, start and stop the timer with the activity, and read and record the measured duration?”
