23. Fluency Complete the table. You may use clocks to help you. 10 1 25 1 40 1

24. Fluency If an event starts at 20 to 4 and finishes at 10 past 5,how long did it last? 1 hour and25 minutes 1 hour and30 minutes 1 hour and35 minutes 1 hour and30 minutes If an event starts at quarter to 10 and finishes at 10 to 11, how long did it last? 1 hour and5 minutes 1 hour and5 minutes 1 hour and10 minutes 1 hour and15 minutes

25. Fluency Complete the table. You may use clocks to help you. 25 past 2 20 past 5 10 to 11

26. Fluency Complete the table. You may use clocks to help you. 20 past 8 Quarter past 5 25 past 10

27. Reasoning Spot and correct the duration mistakes. Event A duration = 1 hour and 20 minutes. Event B duration = 2 hour and 35 minutes.

28. Problem solving Create a timetable from 8 o’clock in the morning to 3 o’clockin the afternoon. Write the start time and end time for each event. Go for breakfast – 1 and a half hours. Park – 1 hour and 20 minutes. Lunch– 2 hours. Swimming – 1 hour and 25 minutes. Recycling – Three quarters ofan hour.

29. Lesson 4 Step: Compare durations of time

30. Fluency Which is the longest duration? 40 minutes 25 minutes A quarter of an hour Three quartersof an hour Half an hour 

31. Fluency Which is the shortest duration? Half an hour 25 minutes  35 minutes 40 minutes Three quartersof an hour

32. Fluency Order the durations, shortest to longest. Half an hour 55 minutes 40 minutes 25 minutes Three quartersof an hour 25 minutes, half an hour, 40 minutes,three quarters of an hour, 55 minutes.

33. Fluency Order the durations, longest to shortest. Three quartersof an hour 35 minutes 5 minutes 15 minutes 1 hour 1 hour, Three quarters of an hour,35 minutes, 15 minutes, 5 minutes.

34. Fluency Use the table to complete the sentences. Golf Which event had the longest duration? ___________________Which event had the shortest duration? ___________________How much longer did football last than swimming? ____________________ How much shorter did rugby last than football? ____________________ Swimming 1 hour 5 minutes 20 minutes

35. Reasoning Will all activities be completed in an hour?How do you know? Yes, as the total duration is 55 minutes.

36. Problem solving Complete the sentences to make them true. ________________ lasts for ________ minutes.________________ is longer than ________________ and ________________. ________________ is shorter than ________________ and ________________.________________ is longer by ________ minutes. ________________ is shorter by ________ minutes. ________________ > ________________. ______________ < ________________.
