Measure Our Heights

Age 5 to 7 Challenge Level:

 
The first boy boy is trying to find out how tall he is.  I think he is finding it hard.
In the second picture the little boy is trying a different way, but still finding it hard.

 


This girl is being measured in a different way and the others are discussing how good that way is for finding her height.

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 m as well as cm ?
