Fractions addition and subtraction with different denominators. KS2 Year 6, but great for revision in KS3, and essential for foundation GCSE, and not a few higher candidates would benefit too.
Warm up worksheet that asks the learners to find common multiples and common factors, through word questions.
Colourful presentation covering the definitions of a fraction, and why the numerator has to be the same. One example, and then a small selection for the learners to find the lowest common denominator.
Finally a worksheet for the learners to try out, or revise, these new skills.
Does not include addition of mixed numbers - all simple results less than one.
All worksheets in Word and PDF, and all answers included! The presentation has been updated to include an older version of PowerPoint, a revised v2 which might fit better, and a PDF version which will work on any system.
Year 6 specs say:
‘use common multiples to express fractions in the same denomination
add and subtract fractions with different denominators’
