YEAR 1 Measurement: Time Telling time to the half hour Writing time Comparing time Block 6 – Week 11

Lesson 1 Step: Telling time to the half hour

Recap: What do the big hands and small hands mean on a clock? The big hand is the minute hand. It tells us how many minutes past or to the next hour. The small hand is the hour hand. This tells us which hour it is.

For half past times, the minute 6 hand will always be on _______. What will happen to the hour hand? It will go half way between the ________________ current hour and the next hour.

Which clock shows half past 4?

Which clock shows half past 10?

What time is shown? Half past 2 Half past 12

What time is shown? Half past 7 Half past 3

What time is shown? Half past 1 Half past 6

On your clock show: Half past 5 Half past 8

On your clock show: Half past 12 Half past 7

On your clock show: Half past 9 Half past 3

Mo has positioned the hands to show half past 4. What mistake has Mo made? The hour hand should be half way between 4 and 5. Can you show or draw the correct time on the clock?

Problem solving Three hours later than half past 10 is half past 1 __________. Five hours before half past 2 is half past 9 __________. Can you create your own time sentences?

Lesson 2 Step: Writing time

What device could we use to measure the length of time of an activity? A stopwatch can be used to measure seconds, minutes or hours. Fluency

Fluency Order from shortest to longest. hours seconds minutes hours

Fluency What unit of time would the activity be best measured in? seconds minutes Writing the numbers 1 to 5. hours

Fluency What unit of time would the activity be best measured in? seconds minutes Getting the bus from London to Manchester. hours

Fluency What unit of time would the activity be best measured in? seconds minutes Taking the dog for a short walk. hours

Fluency What unit of time would the activity be best measured in? seconds minutes Pouring a cup of juice. hours

Fluency What unit of time would the activity be best measured in? seconds minutes Read one chapter of a book. hours

Fluency Complete the sentences. seconds hours minutes Can you create your own time sentences?

Reasoning Complete the table. True False One minute is shorter than one second. I would measure a Maths lesson in seconds. One hour is longer than one minute. Boiling an egg would be measured in hours. Running three laps around the school playground would be measured in minutes.

Discuss the questions with your partner. Name three activities that you would measure in seconds. Name three activities that you would measure in minutes. Name three activities measured that you would measure in hours. What device would you use to measure the duration of an activity?

Lesson 3 Step: Comparing time

Year 1 recorded the time it took them to complete a race. Complete the sentences using faster or slower. Che 35 seconds Kat 30 seconds slower than Kat. Che is ________ faster than Matt. Kat is ________ faster than Che. Matt is ________ Matt 33 seconds

Year 1 recorded the time it took them to complete a race. Complete the sentences using faster or slower. Asha 31 seconds Ben 34 seconds faster than Ben. Asha is ________ slower than Jess. Ben is ________ faster than Asha. Jess is ________ Jess 28 seconds

Busses left the station in the afternoon. Complete the sentences using earlier or later. Bus A Bus B later than Bus B. Bus A leaves ________ earlier than Bus C. Bus B leaves ________ later than Bus A. Bus C leaves ________ Bus C

Busses left the station in the morning. Complete the sentences using earlier or later. Bus A Bus B earlier than Bus B. Bus A leaves ________ earlier than Bus C. Bus B leaves ________ later than Bus A. Bus C leaves ________ Bus C

Three children recorded their times for a swimming competition. Kat My time was between 32 and 35 seconds. 1 st – Kat 2 nd – Che Jess 3 rd – Jess My time was 4 seconds faster than 27 seconds. True or false? Che My time was slower than Kat’s time. False. 1 st = Jess, 2 nd = Kat, 3 rd = Che. Reasoning

Year 1 recorded the time it took them to complete a race. Complete the sentences to make them true. Jack: 42 seconds Dom: 40 seconds Tam: 38 seconds Dom is slower than ______Tam ______ but faster than ______. Jack Dom is faster than ______ Jack ______ but slower than ______. Tam Can you create your own comparison sentence?

Lesson 4 Step: Comparing time (Practical)

Fluency Practical: Select two time cards. Compare the time using earlier than, later than or equal to. All times are afternoon/evening so start at 12 o’clock.

Reasoning Spot and explain the mistake. All times are afternoon / evening times. is later than but earlier than Half 1 is later than 12 o’clock but NOT earlier than half 12. Half 1 is later than 12 o’clock and also later than half 12.

Using the clocks, complete the comparisons to make them true. ______ is later than ______ but earlier than ______ is earlier than ______ but later than ______ is later than _______ and also later than ______ is earlier than ______ and also earlier than ______. Problem solving
