Measurement
In Year 4 your child moves from simply reading measurements to converting and calculating with them. They learn to change between units such as kilometres and metres or hours and minutes, find the perimeter and area of rectilinear shapes, compare amounts of money in pounds and pence, and tell the time on both analogue and 24-hour clocks. This is the year measurement starts to join up with the rest of maths, so a confident grasp here makes word problems much easier later on.
Practise Measurement
Have a guess, even if you're not sure. Get one wrong and we'll show you why, so every miss is a chance to learn.
Timed practice
The same practice, just with a gentle clock. Pick a length and see how many you can answer.
Each quiz keeps things small and clear. Where it helps, questions come with a picture, such as a shape to count squares around or a clock face to read, so your child can see what is being asked. The questions build in gentle steps rather than jumping ahead, and if an answer is wrong a short hint points the way without giving it all away. Your child can take their time and try again.
