Converting between units of time

  • Year group: Year 4
  • Term: Summer
  • Topic: Time
  • Duration: 1 weeks
  • Keystage: KS2
  • Age Range: 8 to 9 yrs
  • Unit can be taught out of sequence: Y
  • Week Range: 5

In this chapter, pupils start to solve problems in which they are required to convert between units of time.

Knowledge of the number of days in a week, months in a year, seconds in a minute and minutes in an hour can now be applied in conversion-focused word problems. At this stage, pupils convert from the larger to the smaller unit (eg, from minutes to seconds), so that the quantity of units increases rather than decreases, thereby avoiding the complexities of rounding.

Pupils should move confidently between analogue and digital (12- and 24-hour) clocks, reading and writing the time from them.

White Rose Maths

Reasoning - Problem Solving Questions - 30th March

Today's problems are ones that require children to think carefully about what they have to do. There are two problems for KS1 and two for KS2.

In KS1 problem children have to use information about two plates of food to work out the cost of a fried egg. They then have to work out time problems.

At KS2 children potentially need to use all four operations and the problems can be solved using bar modelling. The first one is similar to the train and football one from last week, except the picture doesn't make the approach as obvious.

Every day in March the White Rose Maths Hub is aiming to put out a question of the day.

Mathematics Mastery

Converting between units of time

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of converting between units of time.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Like what you see? Mathematics Mastery is a professional development programme for teachers with a mission to transform mathematics education in the UK.

This task is just a taster of the complete classroom resources we offer. We also provide in-depth development training, online CPD, specialist support and assessment tools.

We believe all elements of our programme are vital in creating lasting change – enabling every child to enjoy and succeed in mathematics.

Converting between units of time

Enabling pupils to develop their mathematical reasoning skills through independent work is a key element of the Mathematics Mastery programme.

This activity explores the concept of converting between units of time

• Pupils should complete these tasks using concrete manipulatives as part of the CPA approach
• Pupils should be encouraged to explain their working in full sentences
• These tasks may be adapted with pupils working in pairs to encourage mathematical discussion

Year 4 Measurement: Time – White Rose Summer Block 3 Week 5

This pack of resources covers Year 4 Measurement: Time for week 5 of the summer term.

Week 5 includes worksheets and activities on:

Hours, minutes and seconds
Years, months, weeks and days
Analogue to digital 12 hour
Analogue to digital 24 hour
Calculating the duration

In the worksheets, time is represented in a variety of ways and lend themselves well for use alongside concrete manipulatives and pictorial representations.

The resources include pictorial and abstract representations as well as reasoning and problem solving activities and more open ended problems to support and extend your whole class.

We hope you find these worksheets useful and save you time planning. We aim to produce resources which are of the highest quality - we strongly believe that the visual aspects of these worksheets enable deep understanding of the areas being taught. Once you have used these resources, we would love to hear what worked particularly well and what could be improved on: we often edit our resources.

Thank you for taking your time to browse this resource!

Adding and subtracting time - Solar system time zo

Children use 'Earth&' times as a base. They must add or subtract set amount of time (e.g. 1hr 30mins) to each of the earth activity times. Good exercise for adding and subtracting time accurately

Time

A week´s lessons teaching analogue to digital conversion, telling the time and adjusting using timetables. Week plan included with last lesson intended to make a clock. Just beware: forty is misspelt on one of the slides!! Oh my dear god!!! But, that just means you can change it. After all, I wouldn't want you to have a totally free ride.

Converting time 24 hour time (level 4)

Full lesson on converting 24 hour time. The lesson takes students from converting minutes, seconds, hours etc. through to converting to and from 24 hour time. The starter can be ignored, it is something I am doing with all my classes. Let me know what you think
