Classroom Ideas

This clip could be used as a lesson starter to introduce conversions of units of time - from months, into years and months and weeks, into months and years. Pupils will be able to use their knowledge of how many days there are in a week to build up multiples and remainders, to arrive at sensible solutions. There are two differentiated questions that are closed and an open-ended question that could be the stimulus for further time investigations.
