In working with fractions students learn how to compare fractions and mixed numbers with different denominators using equivalences. They progress on from this by adding and subtracting fractions using visual and written methods.

This unit takes place in Year 7 Term 4, and is followed by multiplying and dividing with fractions in Year 8.

- Compare and order fractions whose denominators are all multiples of the same number
- Identify, name and write equivalent fractions of a given fraction, represented visually, including tenths and hundredths
- Recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number
- Add and subtract fractions with the same denominator and denominators that are multiples of the same number
- Use common factors to simplify fractions; use common multiples to express fractions in the same denomination
- Compare and order fractions, including fractions > 1

- Equivalent fractions are found by multiplying the numerator and denominator by the same number or term. Students often benefit having a visual representation back up the written method.
- To convert between mixed numbers and top heavy fractions students often benefit from drawing diagrams to back up their written methods.
- To simplify a fraction the numerator and denominator are divided by their highest common factor.
- When comparing fractions less able students benefit from using the fraction wall. More able students should use equivalent fractions as the written method.
- Similar to comparing fractions when performing addition and subtraction students can use a fraction wall to visualise the increased or decreased amount.
- The lowest common multiple is used to make the denominators equal when adding and subtracting fractions.

Develop fluency

- Consolidate their numerical and mathematical capability from key stage 2 and extend their understanding of the number system and place value to include decimals and fractions.

Reason mathematically

- Extend their understanding of the number system; make connections between number relationships, and their algebraic and graphical representations

Solve problems

- Develop their mathematical knowledge, in part through solving problems and evaluating the outcomes, including multi-step problems

Number

- Order positive and negative integers, decimals and fractions; use the number line as a model for ordering of the real numbers; use the symbols =, ≠, <, >, ≤, ≥
- Use the four operations, including formal written methods, applied to integers, decimals, proper and improper fractions, and mixed numbers, all both positive and negative

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have. Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]

When learning how to write 3-part ratios students need to understand how ratios can be made equivalent. The start of the lesson reminds students by asking which of six ratios is the odd one out. This is presented to the class as they come into the lesson. Writing Equivalent Ratios A few students immediately go […]
