**5 key approaches to deepening understanding for greater depth in Maths at Year 5 and 6 in primary schools.**

In the last few years mathematics teaching and learning has changed; transformed in the way it is taught and learned at primary school.

Mastery approaches, higher standards and depth (rather than coverage) agendas are paving way for greater conceptual understandings in mathematics for all. But what does that mean?

Considering mastery is an approach to teaching and learning which has high expectations for all learners at its core, this really means that everyone should be aiming for deep understanding in mathematics if they are using a mastery approach to teaching and learning.

As a Year 6 Teacher, KS2 Leader and Mathematics Coordinator, teaching deeper understanding in Maths is something close to my heart (and professional experience!)

**In this blog, I’ll share with you my five key ingredients to building greater depth in Year 5 and 6 Maths…**

**1. Teaching for Greater Depth in Year 5 and 6: Grouping Strategies**

All children progress through content largely at the same time. Traditional differentiation, based on levels is out, in favour of challenge which provides opportunities to demonstrate depth of understanding.

Note: *This does not mean that all children must do the same work in each session.*

There are many ways differentiation can be achieved including access to concrete, pictorial and abstract resources, differentiated activities or offering all children the same starting point and subsequently varying tasks as the lesson progresses (more on variation theory later).

This approach can often lead to collaborative approaches to teaching and learning with fluid groupings rather than fixed groupings.

**Some grouping strategies to deepen understanding are:**

**•** Random grouping

**•** Cumulative partners (starting with 2 children and ‘growing’ as the lesson progresses)

**•** Mixed ability grouping – one child is the teacher; the other completes the task

**•** Ability grouping (based on the topic being taught, some children may be excellent at shape but need support with statistics)

For more on mixed ability vs ability grouping, read this blog post.

**2. Teaching for Greater Depth in Year 5 and 6: Curriculum Design**

I saw a viral image recently which I thought illustrated depth and mastery very well…try drawing the Burger King logo from memory on a piece of paper.

At first it may be a little sketchy, until you have revisited the shop at different times, or spotted it on your television, internet, mobile device or even magazines.

After all that exposure, eventually you’ll be able to fluently recall it from memory and explain the logo to a friend clearly. See below for a great example of this in practice:

That is what a depth curriculum in mathematics should look like. It should always include exposure and consideration to key concepts over and over again in different contexts. It’s the key, really.

To embed frequent exposure to key topics into your lessons, use starters mini revision sessions. This will allow children to revisit concepts and ‘join the dots’ between learning (even across different topics).

The gradual building of fluency through revision will speed up their journey towards greater depth.

For example, should children have looked at time recently, you may link this with angles by asking the question:

‘Two clock handles are at 90° to each other, which times could it be?’

## Use these KS1 and KS2 activity sheets to secure and embed key time concepts such as: o’ clock, half past, quarter past, and the position of the minute hand

**3. Teaching for Greater Depth in Year 5 and 6: Multiple Representations**

Representing mathematics in different ways is essential to deepen understanding of the mathematics at play in Years 5 and 6.

Much of the research suggests representing using concrete, pictorial and abstract approach has long lasting impact on understanding. This Piagetian theory allows children to assimilate new representations when new concepts are taught.

Third Space have a great blog on using bar models to represent SATs style problems which you can find here. Or you can download their worksheet of 25 worded problems complete with bar models here.

**4. Teaching for Greater Depth in Year 5 and 6: Variation**

Variation theory goes beyond procedure by creating an appropriate route for practicing thinking processes with increasing creativity. It offers a systematic approach to facilitate children to notice patterns and make links.

I have been trying out activities using variation theory in my classroom recently: varying tasks through structure or scaffolding.

For example, should you be focusing on place value you be offer conceptual resources which represent the same mathematical idea (such as place value grids, Gattegno boards, place value counters and/or a 100 square).

Similarly, procedural variation allows children to discuss relationships, patterns and hypothesise mathematically by extending the original activity by a given variable. Take this set of questions, for example from Yee Lai and Murray, 2012:

Deepening Problem 1: There are 9L of apple juice and every 3L is put in a jar. How many jars are needed?

Deepening Problem 2: There are 9L of apple juice and every 1L is put in a jar. How many jars are needed?

Deepening Problem 3: There are 9L of apple juice and every 0.3L is put in a jar. How many jars are needed?

Deepening Problem 4: There are 9L of apple juice and every 0.1L is put in a jar. How many jars are needed?

Deepening Problem 5: There are 9L of apple juice and every 0.05L is put in a jar. How many jars are needed?

Or (to show how this could work for Year 5 and 6 in primary school), you could present problems to children in this way:

Here, the conceptual variation of part of 1/4 being relational to the size of the whole will allow children to reason and develop a deep understanding of fractions.

This problem could be done in a practical context using Lego/Cuisenaire rods, or pictorially by allowing the children to draw the problem out without the cover included.

To vary this, the context may be changed to halves, thirds, fifths etc. Which will allow you to elicit ‘what’s the same, what’s different?’ questions.

**5. Teaching for Greater Depth in Year 5 and 6: Intelligent practice**

To illustrate this in a way that promotes intelligent practice while still using variation theory – consider this pie chart:

The blue represents 1/2 or 50%, the red represents 1/3 (or 2/6) and the green represents 1/6.

Try asking ‘What’s the same, what’s different?’ style questions to promote greater depth by using these questions stems:

**•** If there are 120 people, 60 walk, 40 take the car and 20 cycle.

**•** If there are 240 people, __ walk, 80 take the car and 40 cycle.

**•** If there are 360 people, __ walk, __ take the car and 60 cycle.

**•** If there are 480 people, __ walk, __ take the car and __ cycle.

**•** If there are __ people, 30 walk, 20 take the car and 10 cycle.

**•** If there are __ people, 60 walk, 40 take the car and 20 cycle.

**•** If there are __ people, 90 walk, 60 take the car and 30 cycle.

Once children have practiced this intelligently, they can write their own statements about the model.

A procedural variation may also explore patterns, rules and systems such as:

3 x 2 = 6

3 x 20 = 60

3 x 200 = 600

30 x 20 = 600

300 x 200 = 60,000

And then varying the position of the equal sign can vary this further

6 = 3 x 2

60 = 20 x 3

600 = 200 x 3

**So there you have it, my five key ingredients to embedding greater depth in Maths for Year 5 and 6. I hope you find them useful. For your pupils – depth of understanding should allow for opportunities in which mathematics can be actively and intelligently practiced to develop deep conceptual understanding.**
