Pattern around us

How do you know

it is a pattern?

What is pattern?Any predictable regularity, usually involving numerical, spatial or logical relationships.. In early childhood ..Repeating patterns, spatial patterns, and growing patternsThe way the pattern is organised is its structure

Mulligan & Mitchelmore (2009: 34)

The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting patterns is the basis of structural knowledge, the goal of mathematics learning

Shape space and measures: ELG

Children use everyday language to talk about size, weight, capacity, position, distance, time and money to compare quantities and objects and to solve problems.

They recognise, create and describe patterns.

They explore characteristics of everyday objects and shapes and use mathematical language to describe them.

National curriculum Y1 Number & place value: notes and guidance (non–statutory) They recognise and create repeating patterns with objects and with shapes. .. counting in twos, fives and tens from different multiples to develop their recognition of patterns in the number system (for example, odd and even numbers)

Y2Number & place value: notes and guidance (non–statutory)

As they become more confident with numbers up to 100, pupils are introduced to larger numbers to develop further their recognition of patterns within the number system and represent them in different ways, including spatial representations.

Geometry: Statutory requirements ..order and arrange combinations of mathematical objects in patterns and sequences

notes and guidance (non–statutory)

..work with patterns of shapes, including those in different orientations.

Pilot Framework ELG Number:

Children at the expected level of development will:

• Have an understanding of number to 10, linking names of numbers, numerals, their value, and their position in the counting order;

• Subitise (recognise quantities without counting) up to 5;

• Automatically recall number bonds for numbers 0-5 and for 10, including corresponding partitioning facts.

Page 11: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

Pilot Framework: ELG Numerical Patterns

Children at the expected level of development will:

• Automatically recall double facts up to 5+5;

• Compare sets of objects up to 10 in different

contexts, considering size and difference;

• Explore patterns of numbers within numbers

up to 10, including evens and odds

Different kinds of patterns in the early years curriculum

• Regular arrangements eg dot patterns

• Repeating patterns: ABC, ABC,..

• Growing patterns: staircases; 2,4,6,8

• Reflecting patterns:

Recognising patterns

Page 16: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

Why is pattern important?

• Pattern awareness predicts later mathematics achievementRittle-Johnson et al (2016)

• Students who recognise the structure of mathematical processes and representations acquire deep conceptual understanding.

• High achievers are good at visualising, involving recognition of pattern and structure.

• Low achievers produce poorly organised pictorial and iconic representations. High achievers use abstract notations with well–developed structures

Pattern novices: do they..

• continue third unit?

• edit by changing objects or colours?

• identify errors: extras, swops, missing items?

• fix errors?

How do we develop young children’s pattern awareness in the nursery and

reception?

Whole class and independent learning:Now I’ve got into a mindset of just introduce and show and just put it out there and see what happens.

..Allowing them to explore and get things wrong.. observe what they are doing, not just intervene, listen to their language

Page 44: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

‘Co-worker working’

.. And they do enjoy challenging each other,.. because they can see if somebody else has created a pattern, or if there’s a mistake or if there’s something wrong, they can see that together.

..And its not just maths, its language and its PSED skills, because of the social skills that they have to have.

Moving from linear to continuous patterns

• Linear patterns

• circular patterns

• border patterns:

- turning corners

- fixed number of spaces

Page 50: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

Activity

• Using the materials at your table make a circular repeating pattern around a plate

• What might a child learn?

• What questions might you ask?

• Make a border pattern for 12 or 14

First attempt at bringing the repeated pattern around the shape. R needed a lot of support to work out how to continue her pattern in a different direction

D worked with his friends to continue the pattern. They didn’t keep all of the colours close to the shape however, preferring to ‘make the pattern fit’.Once completed, D commented:‘It’s not fair because we haven’t made the pattern fit properly – look, we’ve left lots of spaces.’ He then set about fixing the problem which meant that his pattern would not ‘work’. D: We need to try a different pattern, ABC doesn’t work. We can try AB first because that’s 2 and it might work better.’

Page 53: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

B starts to change the AB pattern round the square into an AABB pattern because:‘I want to see if an AABB pattern will fit around the square, AB did so 2 works but I don’t know about 4 yet.’ He checks as he goes and lifts the shape at the end. ‘It does work – look! AABB goes on and on all the way round.’

Page 54: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

The girls were investigating all the different formations of patterns they could think of. ‘We won’t do AB because that’s too easy. We can try 3 first.’ The girls found the magnetic letters and decided to use these to see if they could make the pattern work.‘It’s an ABC pattern, we tried it and we writed down that it works – we even did ticks and smiley faces!’ The girls then realised that they had left spaces at the corners and added another unit of repeat to make the pattern complete.

Whole class carpet session. Prior to the children’s arrival, the pattern was laid out for the children to discuss and identify.

D identified an AABB pattern and removed the unit of repeat from the pattern to show the children.

D was challenged to find another unit of repeat and with support from the teacher found that AABB can also be ABBA

Misconceptions still occur – A separated ABA and the other children helped him to see that it wouldn’t work.‘Look, there’s 2 purple ones beside each other so they are the same – you’ve just got 1.’ The child came and demonstrated.

Page 56: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

The picture was presented as a pattern to the children and they were asked to identify the unit of repeat.

All said AABBC - identified shoe, shoe (AA), glove, glove (BB), duck (C).

After discussion – they agreed it could be ABC as it was 1 pair of shoes (A), 1 pair of gloves (B) and 1 duck (C).

T brought up ABCDE suggestion – each shoe is different (AB), the hands are different (CD) and then the duck (E). The children would not accept this as an answer.

Page 57: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

Children are encouraged to think for themselves.A didn’t want to use the shapes but also didn’t want do a ‘boring’ straight pattern. She found the pencils and chose 3 colours, then laid them out before her.‘It’s an ABCC pattern – see. The red one is just 1 so it’s on its own, so is the yellow one – that’s the B, but the orange is 2 so they have to be beside each other not in a line. Then it’s A, B, then CC and then it happens again and again!

Page 58: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

The children worked together to create a pattern using AABC and then separated the units of repeat out so everyone could see.

‘There’s 3 units of repeat and there’s 3 of us, we can put our names on 1 each!’

Will an ABB pattern work?

What about ABA? ABBC?Vote!Why? Why not?

AABBC pattern, 12 spaces:“So its 5 and 5 and 2 more, so it’s not enough and I need 3 more to make it”.

AABB works: ‘Because it’s four, three times’.

Key points in teaching pattern

Copying and comparing patterns: noticing

What is the same and what is different?

Identifying repeated relationships

Unit of repeat: underpins measuring (repeated units) and multiplication (counting groups)

Abstracting and generalising: same structure, different context

Page 75: The Pattern Project - North-East Hants and Surrey Maths Hub · The power of mathematics lies in relations and transformations which give rise to patterns and generalisations. Abstracting

Early algebraic thinking

• noticing mathematical features

• identifying the relationship between elements

• observing regularities
