An archaeologist uses a ruler to measure a piece of leather. He measures using centimetres and tenths of centimetres. The leather measures 3.3cm. A thermometer is set out in intervals of tenths of a degree and records a temperature of 27 degrees.

This clip can be used as part of a lesson on mastering measuring equipment. Each pupil can be given a marked ruler and thermometer and asked to record the length and temperature as they think they are displayed. The clip can then be shown and pupils can be given the opportunity to alter their recordings if they deem it necessary. This could be an assessment for a learning activity where the teacher would be easily able to see whether pupils' understanding has developed. They would also be able to identify which pupils still have trouble with measuring in this way.
