Teaching idea: Allow the pupils to work on this activity without any help. Once they have arrived at an answer, collect ideas from the class about strategies used then give the pupils a chance to re-estimate the lengths. As a point of reference, the classroom door is probably around 2m tall. Use a large ruler to find the correct lengths but stress that getting the answer exactly right was not expected.

Click here to obtain another set of random lengths if you would like to repeat the exercise.
