Mental Oral Starters Y5 Summer Teaching Sequence M4

Activity 1

Objective: Write 12-hour digital times

Resources: Counting stick

·  Point to the centre of a counting stick. This is 12 o’clock. Each division is 1 hour. Point to 1 o’clock. What time goes here? Write the 12-hour digital time on your whiteboards.

·  Count in steps of 1 hour from 9:30 to 2:30 and back first saying the time in analogue form (half past nine, half past 10…) then in digital form (nine thirty, ten thirty…).

·  Point to various places on the counting stick including half hours asking children to write the digital time on their whiteboards.

Activity 2

Objective: Convert analogue to 12-hour digital times

Resources: ITP Tell Time (see resources)

·  Use the ITP Tell Time, choosing the 12-hour digital option. Click to hide the digital clock. Show a time on the analogue clock, children write the digital time on their whiteboards. Reveal the digital clock to check.

·  Repeat, including ¼ past and ¼ to the hour, as well as times where the minutes are not multiples of 5, e.g. 12:48.

Activity 3

Objective: Know pairs to 60

Resources: Bean bag, analogue clock

·  What is ½ of 60? ¼ of 60? ¾ of 60?

·  Call out 48. Throw a bean bag to a child who replies 12 (to make 60) and throws it back.

·  Repeat calling out different numbers less than 60 (including multiples of 5 for less confident children) and throwing the bean bag to different children asking them for the complement to 60.

·  Show some of these pairs on a analogue clock face.

·  It’s 10:48, how long until 11 o’clock? Throw a bean bag to a child who replies 12 and throws it back.

·  Repeat saying other times between 10 and 11 o’clock, children respond with the number of minutes before 11 o’clock.

Activity 4

Objective: Say the time after a number of minutes

Resources: ITP Tell Time (see resources)

·  Use the ITP Tell Time, choosing the 24-hour digital option. Show 11:55 on the digital clock. Write the time which is 10 minutes later on your whiteboard. Five, four, three, two, one, show me!

·  Show 12:55 and other times which require children to bridge the hour, they write the times 10, 15 or 20 minutes later.

Activity 5

Objective: Find time intervals

Resources: None

·  Children work in pairs to find as many pairs of times as they can in 5 minutes between 12:30 and 13:30 with a difference of 47 minutes.

·  Discuss how they did this, for example finding pairs of numbers that add up to 47 to bridge 13:00.
