**Here’s why you should make sure your Year 6 have great arithmetic skills for success in KS2 SATs. It’s not just about the KS2 Arithmetic Paper – although it help! **

When faced with the seemingly endless list of content and objectives to cover we have to stick to we have to get the basics right, and build from there. In other words – we have to work on pupils’ KS2 arithmetic skills.

**Arithmetic skills are at the core of Maths teaching**

While your immediate goal may be your pupils achieving ARE in their KS2 Arithmetic Paper, in fact Arithmetic is at the core of almost every single Maths teaching area and essential to their KS2 Reasoning Paper too!

Fluency in numbers is an essential first stage to developing conceptual understanding.

Below we explore 8 reasons why it is important to focus on teaching excellent KS2 arithmetic arithmetic skills, and how to get it ‘right’.

Don’t miss the free downloadable resource Fluent in Five, of daily arithmetic challenges for upper & lower KS2.

**1. Arithmetic skills are essential building blocks for Maths**

Think of an area of Maths. Chances are, you’ll need good arithmetic skills to succeed in that area.

Fractions, percentages, ratio, measures, and statistics. These are all areas where the vast majority of questions require pupils to be fluent in arithmetic to successfully answer.

**2. Arithmetic skills are essential for ‘real life’**

Arithmetic skills are used by adults and children alike throughout their daily lives. Have a think about what you have done so far today: it’s almost certain that you will have used some form of mental arithmetic.

Did you work out how much longer you’ve got until you need to get out the house this morning? Maybe you looked at your speedometer to work out how much to reduce or increase your speed by? Or you might have worked out how many children were absent from your class this morning.

If you’ve done any of these things, you have used arithmetic. We constantly rely on our arithmetic skills in daily life, without even realising it. Which is why it’s so important to build those skills early on.

**3. Developing conceptual understanding of arithmetic saves time on calculations**

Developing a conceptual understanding of arithmetic is hugely important. After all, for pupils to confidently carry out calculations, they need to understand why calculations work, not just the steps to a successful answer.

This is why rote learning of times tables etc. is often actively discouraged. As it encourages the view that Maths is a set of facts and processes, rather than an interconnected subject that is full of flexibility.

When pupils have a conceptual understanding of their arithmetic skills, they are more likely to be able to carry out questions mentally, saving all important time.

Free resources like our Fluent in Five weekly packs can be used to help pupils make quick decisions about when to use the mental method and save time in exam situations.

**4. Fluency in arithmetic helps pupils to flexibly approach Maths problems**

When pupils are fluent in arithmetic, they begin to understand the flexibility needed to succeed in Maths, and the different ways that a Maths problem can be approached.

For example, if you ask pupils to double 36 in their heads, and then explain to their partner how they did it, you’ll witness many different approaches. Some may double 30, double 6 and add the results. Others might double 40 and take away 8. Some might even double 35 and add 2.

Of course, there is no ‘best’ way in Maths. Yet, understanding the ways that Maths is connected and having true fluency in arithmetic helps children to understand and approach almost any problem.

**5. The KS2 Arithmetic Paper is highly weighted in KS2 SATs**

In Key Stage 2 SATs, the Arithmetic Paper accounts for 36% of a child’s overall KS2 Maths SATs raw score, that’s 40 out of 110 marks! In 2017, only 51.8% (57 out of 110 marks) was required to meet the expected standard and gain a scaled score of 100.

When schools analyse their SATs result breakdown (see this great free SATS 2017 QLA resource for help with this), they often find that children that score well in the Arithmetic Paper are more likely to score well and in their Reasoning Papers. Therefore, they achieve expected standard.

**6. Fluent arithmetic Skills are also needed to succeed in KS2 Reasoning Papers**

There are also a high proportion of arithmetic focused marks in the KS2 Reasoning Papers.

According to the official content domain coverage of the 2017 SATs, In 2017, 32 (out of 70) assessed reasoning through arithmetic focused content objectives.

This doesn’t count questions which primarily cover another area (e.g. percentages, measures, number properties) but contain an arithmetic element.

**7. Pupils need to correctly identify and apply written/mental strategies for the KS2 Arithmetic Paper**

In 2017, only 13 (out of 40) marks for Arithmetic Paper 1 were allocated to questions likely to require a written method, with only 4 two marks questions.

However, with the paper designed to include squared working areas after each question, pupils often take up time time carrying out mental questions using a written method. As such, they’re not able to complete the full paper – when they might be fully capable of answering the final questions!

Clearly, having a level of fluency in arithmetic that allows pupils to identify (and correctly apply) written/mental arithmetic methods is key to fully accessing KS2 Arithmetic Paper 1.

Use our new Fluent in Five daily arithmetic practice packs to help your pupils develop the fluency and speed required to complete the full arithmetic paper (and identify between written and mental methods).

**8. Maths Arithmetic skills need regular practice to maintain true fluency**

This isn’t a “why” arithmetic is important, so much as how to best to teach it. Pupils need to be using their arithmetic skills each and every day in order for them to maintain the confidence and fluency needed to successfully tackle their exams.

Why not try using this free Fluent in 5 Daily Arithmetic Practice Pack with your pupils. Covering Years 3-6, it’s perfect for helping pupils understand and apply written/mental strategies, and build arithmetic skills through regular practice.
