Adding and subtracting fractions with different denominators

  • Year group: Year 6
  • Term: Autumn
  • Topic: Fractions
  • Duration: 1 weeks
  • Keystage: KS2
  • Age Range: 10 to 11 yrs
  • Unit can be taught out of sequence: N
  • Week Range: 8

In this chapter, pupils draw on all of their previous knowledge to confidently add and subtract fractions with different denominators.

It is essential that pupils are secure in their understanding of what a fraction is and in the function of a fraction as division, as an operator, as a number and as a decimal.

Pupils use their knowledge of equivalent fractions, and factors and multiples, to simplify fractions of any size. They then compare and order any number of fractions and build on their knowledge of fractions as division to be able to calculate decimal equivalents (eg, 3⁄8 = 0.375). They also add and subtract any fractions using the concept of equivalence.   

Concrete objects and visual representations should be used throughout to help explain key concepts and allow pupils to make the links between the calculations.

Problem Solving Question of the Day - 1st March

In March the White Rose Maths Hub want to provide primary teachers with a KS2 problem of the day. These are all reasoning and problem solving questions that teachers can use on daily basis in their classroom. Some problems may be suitable also for some students in KS3 and GCSE.

If your class solve the problem during March why not tweet us a picture of their solution @WRMathsHub

Mathematics Mastery

Adding and subtracting fractions with different denominators

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 adding and subtracting fractions with different denominators.

• 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.

Adding and subtracting fractions (differentiated)

Two worksheets to help practise adding and subtracting fractions. Worksheet 1 concentrates on fractions with the same denominators. Worksheet 2 has fractions with different denominators.

Introduction to Fractions - hands on exploration

A practical support to gaining a concrete understanding fractions and how they work. The whiteboard file (Promethean only I'm afraid) allows teacher / pupils whole class discussion. The pupil cards (classroom assistant needed! Different colour card for each fraction is best) for pupils (1 set for one / two pupils). Work-cards allow for some independence (if you want). Also included is a link to the fractions ITP - different representations of fractions help a great deal.

Adding fractions (different denominators)

Step-by-step method to put into correct order, and 'tick or trash' activity - finding correct answer, and spotting mistakes on incorrect ones. Good starter/plenary activity.

Arithmagon 5 - Adding Fractions

This a rich, Arithmagon activity on Adding Fractions.

I love Arithmagons as they allow consolidation of key topics when going Forwards, and then opportunities for extension, creativity and discovery when working Backwards. They are also really easy to modify to suit the particular needs of your class.

For all the Arithmagon activities in this series, together with teaching notes and extra information, please visit http://www.mrbartonmaths.com/arithmagon.htm
