Time questions are very popular with the SAT test writers and this page shows some typical examples, using tables and charts.
Children often get confused by questions which say that an event was earlier or later when looking at a calendar. If it was earlier then the number of days have to be subracted. On a calendar moving up one position will subtract 7 days – useful when counting back.
Many more time questions can be found in the year 6 category, under Key Stage 2 Maths SAT Practice.
