This unit of Maths is Measurement: Length & Perimeter.
For your task today you will need a ruler preferably a 30cm but if you only have a smaller one not to worry.
You are going to be measuring using cm's. Have a look at the picture above can you see the difference?
Remember you need to start from the 0 where the black line is not the edge of the ruler.
Your task is to go round your home measuring items and recording them in a table we are going to use some of the skills we learnt in DT of recording our items in a table we want to use, then predicting what size we think they are going to be and then measuring, recording what size they are. See below for an example.
Have fun measuring! Can't wait to see your work.
