Lesson 2 Step: Quarter past and quarter to
Fluency
Fluency What time is shown? Quarter past 5 Quarter past 11
Fluency What time is shown? Quarter past 6 Quarter past 8
Fluency What time is shown? Quarter past 1 Quarter past 3
Fluency On your clock show: Quarter past 4 Quarter past 10
Fluency On your clock show: Quarter past 11 Quarter past 8
Fluency What time is shown? Quarter to 10 Quarter to 1
Fluency What time is shown? Quarter to 8 Quarter to 12
Fluency What time is shown? Quarter to 9 Quarter to 10
Fluency On your clock show: Quarter to 8 Quarter past 2
Fluency On your clock show: Quarter to 10 Quarter past 4
Reasoning It is quarter to 9 so the minute hand should be on 3 and the hour hand should be nearer 8 than 9. Do you agree with Sue? Explain your answer. No, the minute hand should be on 9 and the hour hand will be nearer the 9 than 8.
The time is half past a particular hour. The time is between 7 o’clock and quarter past 9. What could the time be? Half past 7 or half past 8. Problem solving
Lesson 3 Step: Telling the time to 5 minutes
Fluency What time is shown? 5 past 12 20 past 8
Fluency What time is shown? 25 past 1 10 past 12
Fluency What time is shown? 20 to 4 5 to 7
Fluency What time is shown? 10 to 12 25 to 7
Reasoning If the minute hand is on 11 and the hour hand is nearly at 8, the time is 11 minutes to 8. What mistake might Kat have made? The time will be 5 to 8. Kat has looked at the number on the clock rather than working out how many minutes to the next hour.
Problem solving If the time is 20 to 10, what number would the minute hand be on? ____ 8 If the time is 10 past 4, what number would the minute hand be on? ____ 2 If the time is 25 to 8, what number would the minute hand be on? ____ 7
Lesson 4 Step: Telling the time to 5 minutes
Fluency On your clock show: 5 to 2 25 past one
Fluency On your clock show: Ten to 12 20 past 4
Fluency On your clock show: Five to 8 25 to 6
Fluency On your clock show: 20 to 4 10 to three
Reasoning If I add on 15 minutes onto 25 to 7, the time would be 10 to 7. Do you agree with Dom? Yes, Dom is correct, the time would be 10 to 7.
Buses leave at 5 past and 10 to every hour. Problem solving If Mo catches a bus between 9 o’clock and quarter past 11, what buses could he catch? 5 past 9, 10 to 10, 5 past 10, 10 to 11 and 5 past 11.
