Once you know the trick to adding and subtracting fractions with different denominators, you'll have no problem with these problems.

Pupil outcome: I can explain how to compare pairs of non-related fractions by comparing to a half. Key learning points: - In fractions equivalent to a half, the numerator is half the value of the denominator. - When the numerator is more...

Pupil outcome: I can explain with and without an image how to add and subtract related non-unit fractions that bridge a whole. Key learning points: - Fractions need to have the same denominator if you are to add and subtract them. - When...

Pupil outcome: I can explain how to add related unit fractions with and without a representation or image. Key learning points: - Common multiples help you to convert a fraction to a common denominator. - When adding fractions the...

Pupil outcome: I can use equivalent fractions with common denominators to compare non-related fractions Key learning points: - You can use knowledge of common multiples to convert fractions to an equivalent with a common denominator. -...

Pupil outcome: I can solve problems involving adding and simplifying fractions with different denominators. Key learning points: - Fractions need to have the same denominator if you are to add and subtract them. - Common denominators for...

Pupil outcome: I can use the mathematical structures that underpin the addition and subtraction of fractions. Key learning points: - The denominators of each fraction should split the whole into the same number of equal pieces. - The...

Pupil outcome: I can begin to generalise a sequence. Key learning points: - Sequences can be continued using a rule. - This rule can be demonstrated with a diagram. - This rule can be described in words.

Pupil outcome: I can explain with and without an image how to add and subtract related non-unit fractions Key learning points: - You can use knowledge of common multiples to convert fractions to an equivalent with a common denominator. -...

Pupil outcome: I can use knowledge of adding and subtracting related unit fractions to solve problems. Key learning points: - When adding and subtracting fractions with the same denominators you just add or subtract the numerators. -...
