Add and Subtract Fractions Upper KS2

This interactive Powerpoint (consisting of 36 interactive slides plus printables) helps pupils in upper KS2 to add and subtract fractions.


Adding and subtracting fractions is not something that pupils are likely to experience very often in real life (we would be more likely to use their decimal equivalents), so this is a rather abstract topic.


Pupils can start with manipulatives, if needed, then link this use to examples without manipulatives.


One of the confusions for pupils when learning fractions is that they consider the numerators and denominators as positive integers (whole numbers) rather than as representing the relationship between the part and the whole. Pupils need to understand that fractions refer to relative amounts rather than focusing on the two separate numbers (the numerator and denominator) and that fractions answer how much, rather than how many.


In Upper KS2 pupils add and subtract fractions with different denominators and mixed numbers, using the concept of equivalent fractions. Pupils should be familiar with equivalent fractions before working on adding and subtracting fractions with different denominators.


Statements are used to allow pupils to use reasoning with each other when deciding whether statements are true or false and games are included for consolidation and an opportunity to discuss ideas. Problems give pupils an opportunity to apply what they have learned in various scenarios.
