How to express the physical quantities
By providing the speeds in the format of, for example, 10 metre in one second, you are laying the foundation for ideas about speed as a measured quantity. The important point here is that you have control over the language used (i.e. distance (metres) moved in 1 second.)
The reinforcement of language is important. The teacher can model the language and encourage pupils to use the same form of words in any discussion that may emerge. This is a good time to make a clear link between fastest and slowest and the measured quantity speed
