📝 Description

Time Tell - STEM helps learners practice reading clocks and understanding time intervals through guided activities. It supports daily-life mathematics, observation, and practical time-telling skills.

📋 Instructions

Compare the displayed durations, then order or match them as the activity asks. Convert seconds and minutes to the same unit when helpful, and check that equivalent durations stay together.

Mathematics — Time and Duration Interactive duration comparison and matching

Learning objectives

Compare the durations of familiar events using appropriate units.
Order durations from least to greatest and explain the order.
Recognize matching or equivalent time representations.

Concepts and principles

Duration tells how long something lasts; time of day tells when it happens.
One minute equals 60 seconds, so different units should be converted before comparing.
A sensible estimate depends on the activity: a blink, a song and a school lesson have very different durations.

Examples and worked solutions

Which is longer: 90 seconds or 2 minutes?: Worked solution: Two minutes is 120 seconds, which is 30 seconds longer than 90 seconds.

Guided practice

Start the duration-ordering activity and read every duration before moving pieces.
Convert any mixed minute/second values to a common unit on paper, then arrange them.
Use the matching or memory activity to test whether you can recognise equivalent or comparable times.

Expected observations and explanations

Comparing values in one unit makes differences clearer.
A card matched by appearance alone can be incorrect if its duration differs.

Assessment questions and answers

How would you compare 1 minute 40 seconds with 95 seconds?: Answer: Convert 1 minute 40 seconds to 100 seconds, so it is 5 seconds longer.
Why is estimating an activity duration useful before comparing it?: Answer: An estimate helps detect impossible or implausible measurements and provides a sensible reference.
