I know the number of seconds in a minute, minutes in an hour, hours in a day and days in each month, year and leap year
What does this objective mean?
This objective requires children to know that there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day etc.
How might it be assessed in the 7+?
Children may be asked simple time conversion questions. For example:
a How many minutes are there in an hour? ___________________________(1 mark)
b. How many hours are there in a day? ________________________________ (1 mark)
c. How many seconds are there in a minute? ___________________________( 1 mark)
d. How many days are there in a week?_________________________________(1 mark)
They may be asked questions to test their knowledge of the calendar, e.g:
The owl flew from his nest in June and returned three months later. In what month did the owl return to his nest?
How do I teach this to my child?
Use a clock (https://www.visnos.com/demos/clock) to demonstrate to your child that the second hand moves round 60 times in one minute, the minute hand 60 times in one hour, etc. Time your child doing different activities so they get a sense of how long a period of time is in seconds, minutes or hours.
Use a wall calendar to teach your child about months and years.
Starfall provides a useful interactive calendar for teaching time:

This well-known rhyme is a good way to help children remember how many days are in each month:
30 days has September, April, June and November,
All the rest have 31, except for February alone,
Which has 28 days clear,
And 29 in each leap year.
How can we practise this?
Give your child some example questions to work through. (See resources)
Teaching resources:
_I know the number of seconds in a minute, minutes in an hour, hours in a day and days in each month, year and leap yearRelated objectives for Measurement
- I can record and compare time in terms of seconds, minutes and hours; use vocabulary such as o’clock, am/pm, morning, afternoon, noon and midnight
- I can compare and order lengths, mass, volume/capacity and record the results using >, < and =
- I can measure the perimeter of simple 2-D shapes
- I can recognise and use symbols for pounds (£) and pence (p)
- I can find different combinations of coins that equal the same amounts of money
- I can solve problems in a practical context involving addition and subtraction of money in both £ and p, including giving change
- I can tell and write the time from an analogue clock, including using Roman numerals from I to XII, and from a 12-hour digital clock
- I can choose and use appropriate standard units to estimate and measure length/height in any direction (m/cm); mass (kg/g); temperature (°C); capacity (litres/ml) to the nearest appropriate unit, using rulers, scales, thermometers and measuring vessels
