This girl is being measured in a different way, with a friend helping her. Do you think measuring using this method looks easy or difficult?
What things in the pictures might they be finding hard?
Can you find a better way to find out the height of a friend?
What will you use? Try it and see how tall they are.
Can you give answers in metres as well as centimetres?
This problem gives pupils the opportunity to find ways of measuring friends' heights, trying to avoid difficulties. The questions also encourage them to think about the units they are using.
Talk to the children about measuring heights of people, to find out what experiences they have had. Lead them then to consider the two pictures and the difficulties that the boy and girl are having. Discuss these difficulties and encourage them to offer suggestions as to how they think they could do it more accurately.
