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 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.
