Introduction to Units of Time

Hello Year 6! Today, we’re going to talk about units of time. Understanding time is super important for our daily lives. We use time to plan our days, schedule activities, and understand how long things take.

What Are Units of Time?

Units of time help us measure how long something lasts or when something happens. Here are the main units we will focus on:

  1. Seconds (s) – The smallest unit of time. There are 60 seconds in a minute.
  2. Minutes (min) – A larger unit than seconds. There are 60 minutes in an hour.
  3. Hours (h) – A common unit we use every day. There are 24 hours in a day.
  4. Days – The time it takes for the Earth to rotate once. There are 7 days in a week.
  5. Weeks – A collection of days. There are about 4 weeks in a month.
  6. Months – There are 12 months in a year.
  7. Years – This is how we measure a long period. There are 365 days in a year (or 366 days in a leap year).

Key Rules to Remember

  1. Conversion – To convert between units, remember:
    • 60 seconds = 1 minute
    • 60 minutes = 1 hour
    • 24 hours = 1 day
    • 7 days = 1 week
    • 12 months = 1 year
  2. Clock Reading – Clocks show time in hours and minutes.
    • The short hand shows hours.
    • The long hand shows minutes.
  3. AM and PM – AM is for morning, and PM is for afternoon and evening.
    • For example, 7:00 AM is in the morning, and 7:00 PM is in the evening.

Tips and Tricks

  • Using a Timer: When cooking or timing activities, use a timer to count down seconds or minutes.
  • Time Zones: Remember, different places in the world have different times! This is called time zones.
  • Practice: The more you practice reading clocks and calculating time, the easier it will become!
