2   Time and timetables



              Think like a mathematician


              a      Leila goes swimming each day from Monday 2 December to

                   Friday 6 December.

                   How many days does she go swimming?
              b  Ahmed joins a gym club from 1 April to 30 June.

                   How many months is this?

              c      Ros works on a project from Wednesday 11 September to Tuesday

                   8 October.

                   How many weeks does she work on the project?




              Look what I can do!


                  I can read a timetable to solve problems.

                  I can choose and use suitable units to calculate time intervals.




              Check your progress


              1  Here is a digital clock.





                   What time is the same as that shown on the clock?


                     7.07 a.m.              7.07 p.m.              5.07 a.m.             5.07 p.m.


              2  Write quarter to twelve in the morning as a digital time.
              3  Here are five times.


                     6.45 a.m.         Ten minutes to eight            15:30         9.30 a.m.




                      quarter past seven

                   Which time is the ‘odd one out’? How do you know?
