# Maths Year 3/4 Spring Time

Each unit has everything you need to teach a set of related skills and concepts.

## Telling the time(suggested as 4 days)

### Planning and Activities

Day 1 Teaching
Revise telling the time, using Tell the time ITP. Tell the time in 5-minute increments from 9 o’clock, watching progress of the hour hand, then match to digital times. Tell the time in 1-minute intervals.
Group Activities: T with Y3
Y3 -- Read, write and make times past the hour (to 5 minutes) on analogue and digital clocks; some children may use clocks with Roman numerals.
Y4 -- Suggest start and finish times to the nearest minute for a day of given holiday activities. Make and match analogue and digital times to personal activities.

Day 2 Teaching
Match analogue times for the quarter hours to digital times. Stress that after half past the hour, we say that analogue clocks show the number of minutes to the next hour (though they show both minutes past and to).
Further Teaching with Y4
Introduce the 24-hour clock, matching analogue and digital times using Tell the time ITP.
Group Activities: T with Y4
Y3 -- Read, make and write times to the nearest 5 minutes on analogue and digital clocks. Find the time ‘5 minutes later’ or ‘15 minutes later’.
Y4 -- Order times presented in a 24-hour format. Or, match am/pm times to 24-hour clock equivalents in a game of bingo.

Day 3 Teaching
Use an IWB teaching clock to tell the time ‘now’, looking at the 12- and 24-hour digital equivalents. Advance the 12-hour digital clock in 1-hour increments, discussing what might be happening at each of these times.
Further Teaching with Y4
Read times accurately from the 24-hour clock.
Group Activities: T with Y3
Use the in-depth problem-solving investigation ‘Dodgy digital clock’ as today’s group activity.
Or, use these activities:
Y3 -- Order times presented in a range of formats. Or, make and write times on analogue clocks and in digital format.
Y4 -- Create and play pairs or snap games with analogue and digital times using am/pm and 24-hour clock formats.

Day 4 Teaching
Create a human digital clock. Create and convert am to pm times and vice versa. Match to analogue times. Observe the 12-hour analogue interval between 9:15am 9:15pm by watching and counting clock hand rotations.
Further Teaching with Y3
Begin to read the analogue clock in 1-minute intervals; observe digital equivalents using Tell the time ITP.
Group Activities: T with Y3
Y3 -- Read and set/write analogue and digital times.
Y4 -- Calculate start times of TV programmes; convert 24-hour clock times to 12-hour times (and vice versa) and into analogue format.

### Worksheets

Day 1
Y3: Draw clock hands and complete digital displays. Draw clock hands, complete digital displays and write times in words.
Y4: Match written, analogue and digital times. Draw clock hands and complete digital displays.

Day 2
Y3: Draw clock hands, complete digital displays and write times in words – to nearest 5 mins.
Y4: Draw lines to match 12- and 24-hour clock times.

Day 3
Y3: Match written, analogue and digital times; order times.
Y4: Match 12-hour and 24- hour clock times. Give equivalent 12- and 24-hour times.

Day 4
Y3: Convert time between analogue, digital and 24-hour clock times.
Y4: Show 12-hour digital times on an analogue clock; convert to 24-hour time. Convert times between analogue, digital and 24-hour clock times.

### Mastery: Reasoning and Problem-Solving

Y3

• Draw the hands on a clock to show:
10 past 10 10 to 10
11:45 12:40
Quarter past 3
• True or false?
1:50 is the same as 10 minutes to 2.
5 o’clock am is 12 hours later than 5 o’clock pm.
15 minutes before 6 o’clock is 5:15 on a digital clock.
If the hour hand is pointing to VI, it is six o’clock.
If the minute hand points at XI, it is nine o’clock.
• If the clock hands make a straight line on an analogue clock, what times could the clock be showing?

Y4

• How long to the next hour from:
(i) 4:54
(ii) quarter to 12
(iii) twenty past 9?
• How long was each film?
(a) started at 6:15pm and ended at 7:05pm
(b) started at 11:20am and ended at 1:15pm
(c) started at 9:00pm and ended at ten to eleven.
• True or false?
Half an hour after 4:45 is quarter past 5.
16:30 is 4:30pm.
00:30 is half past midday.
Quarter of an hour after 13 minutes to 6pm is 18:02.

In-depth investigation: Dodgy digital clock
Children work out which times will not show correctly because of a faulty segment in the digital display.
