I can measure the perimeter of simple 2-D shapes
What does this objective mean?
This asks that children are able to measure the lengths of simple 2-D shapes and add them together to find the perimeter.
How might it be assessed in the 7+?
Your child may be asked to find the perimeter of a simple shape using lengths already given, or by using a ruler to measure the lengths themselves.
For example…
Using your ruler, find the perimeter of this square:
How do I teach this to my child?
Practise finding the perimeter of a few different shapes. Explain to your child that if they are finding the perimeter of a square, all sides will be the same length. If measuring a rectangle, each pair of sides will be equal.
How can we practise this?
Give your child some example questions to work through (see resources)
Teaching resources:

- 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 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
- I can compare and order lengths, mass, volume/capacity and record the results using >, < and =
- 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
