Maths Year 4 Autumn Measures and Data

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

Tell time to nearest minute: am/pm (suggested as 3 days)

Planning and Activities

Day 1 Teaching
Launch ITP Tell the time. Recap telling the time by moving the minute hand around clock at 5-minute intervals. Establish that there are 5 divisions between the numbers, each of which represents 1 minute. Count marks with children to tell time to the minute. Distinguish am and pm as morning and afternoon/evening.
Group Activities
-- Suggest start and finish times to the nearest minute for a day of given holiday camp activities.
-- Make and match analogue and digital times to personal activities.

Day 2 Teaching
Imagine school started 40 mins later. Find all the activity times, now 40 mins later, crossing the hour as necessary. Record times in both analogue and digital times, and work out time intervals.
Group Activities
-- Calculate the times of films that are showing late at a cinema.
-- Solve word problems that add various time intervals to go through the hour.

Day 3 Teaching
Show children that to calculate time intervals, we can use Frog to find the difference between times like finding a difference between 2 numbers on a number line. Model finding time intervals using Frog, crossing the hour, using both analogue and digital clocks.
Group Activities
Use the ‘Palindromic Time Intervals’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Create and challenge one another with time problems that add various time intervals to go through the hour.
-- Identify start times, finish times and the length of programmes and activities from TV guides and swimming timetables.

You Will Need

  • ITP: Tell the Time
  • Holiday camp sheet (see resources)
  • Small analogue clocks
  • Cinema times sheet (see resources)
  • Internet access (required for Day 2)
  • Children’s TV programme guide
  • Local swimming pool timetable

Mental/Oral Maths Starters

Day 1
Pairs that make 60 (pre-requisite skills)

Day 2
Roman numeral clock (pre-requisite skills)

Suggested for Day 3
Order months (simmering skills)
OR
Units of time (simmering skills)

Worksheets

Day 1
What’s the time? Show analogue and digital forms of a given time.

Day 2
Find the finish time. Calculate the finish time of activities at a sports centre, based on start times and length of activity.

Day 3
Calculate times.

Mastery: Reasoning and Problem-Solving

  • Write the times for breakfast, lunch and tea on a Saturday in digital and analogue format. Make sure you use am and pm correctly.
  • How long to the next hour from:
    (i) 4:54
    (ii) quarter to 12
    (iii) twenty past 9
  • Complete each sentence.
    4:35 + ☐ minutes = 5:05
    11:30 – ☐ minutes = 10:40
    6:14 + ☐ minutes = 7:00
    8:45 + 18 minutes = ☐
  • 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.
    Use Frog to help you calculate these.


In-depth Investigation: Palindromic Time Intervals
Children systematically find palindromic digital times and list them in an ordered way. They convert these to analogue times and calculate the intervals between them.
