Confusing. When changing a fraction to an equivalent fraction we might multiply by 2/2 or 3/3 NOT by 2 or 3. The way these worksheets are designed I feel will cause misconceptions and inaccuracies. Apart from this they are great but for me, sadly unusable.
A simple KS3 powerpoint showing adding and subtracting fractions with the same and different denominators. Tfere's a warm up on LCM and equivalent fractions and some queestions with answers at the end.
This is the third Understanding Fractions pack from TES Topics KS2, which includes an explanatory presentation, exciting interactive games and handy worksheets.
[Please note - this pack is still under construction. Games and worksheets will be added shortly.]

> Adding fractions
This is a great word document worksheet for practising adding fractions. Students take it in turns to add a fraction from each column, then cover their answer up with a counter. The aim is to get 4 in a line! Good revision for KS3 and KS4 students.
