Adding and Subtracting Fractions complete worksheet set

For KS2, KS3 or KS4 maths teachers, this set of worksheets completely develops the concept of adding and subtracting fractions. There are 5 worksheets, broadly covering the following aspects of the concept:

1. Adding and Subtracting Fractions with the same denominators
2. Understanding why fractions with different denominators cannot be added or subtracted without exchanging, and identifying when this is and isn’t required.
3. Adding and Subtracting Fractions where one denominator is a multiple of the other.
4. Adding and Subtracting Fractions where the denominators do not share a common factor.
5. Adding and Subtracting Fractions where the denominators do share a common factor.

These can be used one after the other over a series of lessons exploring the concept, or could be spaced across several years, with enough similarity in the structure that pupils should have memories of working on similar tasks triggered.
