Numerical Patterns
EYFSEYMA-R-D002
Verbal counting beyond 20, comparison of quantities up to 10, and exploration of patterns including evens, odds, doubles and equal distribution.
National Curriculum context
ELG 12: Numerical Patterns. Children at the expected level of development will verbally count beyond 20, recognising the pattern of the counting system; compare quantities up to 10 in different contexts, recognising when one quantity is greater than, less than or the same as the other quantity; explore and represent patterns within numbers up to 10, including evens and odds, double facts and how quantities can be distributed equally. This domain reflects the shift in early mathematics pedagogy towards pattern and structure rather than rote procedure. Verbal counting beyond 20 is specifically framed as recognising the decade pattern (the system), not merely reciting numbers — children who see the structural logic of twenty-one, twenty-two... are far better placed to understand place value in Year 1. Quantity comparison is positioned as a prerequisite to the formal inequality language (greater than, less than) of KS1. The pattern recognition strand — evens, odds, doubles, equal distribution — is a deliberate bridge to the multiplicative reasoning that begins formally in Y2.

Verbal Counting Beyond 20
Keystone knowledge AI FacilitatedEYMA-R-C005
The ability to recite the number word sequence beyond 20 by recognising and applying the structural pattern of the counting system — that after each decade number (twenty, thirty, forty...) the units repeat (twenty-one, twenty-two... in the same pattern as one, two...). This is explicitly framed in ELG 12 as understanding the pattern of the counting system, not merely recitation. It is the earliest prerequisite for place value.
Teaching guidance
Make the decade structure explicit — count in tens on a hundred square, then explore the units repeating. Pause at decade boundaries ('What comes after twenty? After twenty-nine?') to check pattern understanding rather than rote recall. Counting larger quantities of objects provides a meaningful context. Use a hundred square as a visual reference — pointing to each decade row reinforces the repeating pattern.
Common misconceptions
Children commonly make the error 'twenty-nine, twenty-ten' — they apply the within-decade pattern at the wrong point. This reveals that counting beyond 20 is being memorised without understanding the decade structure. The words 'eleven' and 'twelve' (which do not follow the regular pattern) are frequent stumbling points, as are the 'teen' numbers.
Difficulty levels
Beginning to count reliably to 20, though the sequence may break down between 13 and 19 where the pattern is less regular.
Example task
Count as high as you can from 1.
Model response: The child counts: '1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15...' and may become uncertain after 15.
Sometimes counting reliably to 20 and beyond, beginning to notice the repeating pattern in the twenties (twenty-one, twenty-two...).
Example task
Count from 1 to 30. What pattern do you notice after 20?
Model response: The child counts to 30. 'After 20, it goes twenty-one, twenty-two... it's like starting again with the same numbers but with twenty in front!'
Verbally counting beyond 20, recognising the pattern of the counting system and using it to count to at least 50 with reasonable accuracy.
Example task
Count from 1 to 50. What helps you know what comes next?
Model response: The child counts to 50 with confidence. 'I know the pattern — after twenty-nine comes thirty, then thirty-one, thirty-two... The ones part is always the same: one, two, three, four, five, six, seven, eight, nine. Then the tens part changes.'

Quantity Comparison
knowledge AI FacilitatedEYMA-R-C006
The ability to compare two groups of objects or two numbers up to 10 and accurately judge which is greater, which is less, or whether they are the same (equal). This includes comparison by direct matching (one-to-one correspondence), by subitising, and eventually by knowing the relative position of numbers in the count sequence. The language of comparison — more, fewer, less, the same as, equal — is as important as the conceptual skill.
Teaching guidance
Always work with concrete objects before moving to abstract numbers. Line objects up one-to-one to make comparison visible initially. Ask for justifications: 'How do you know there are more?' Introduce the vocabulary 'greater than', 'less than' and 'equal to' orally but do not require formal symbolic notation at this stage. Balance activities and equalising activities (adding to the smaller group to make them equal) develop the concept alongside comparison.
Common misconceptions
Children commonly confuse 'fewer' and 'less' (and adults often model this incorrectly). Some children compare the physical size of individual objects rather than the number of objects — a row of large bricks may be judged as 'more' than a larger row of small bricks. Spreading objects out in a line can mislead children who compare length rather than quantity.
Difficulty levels
Beginning to compare two small groups by matching objects one-to-one or by counting, identifying which has 'more'.
Example task
Here are 3 red counters and 5 blue counters. Which group has more?
Model response: 'The blue ones have more because there are 5 and only 3 red ones.' The child counts each group and compares the totals.
Sometimes comparing numbers and quantities using 'more than', 'fewer than' and 'equal to', with growing confidence and accuracy.
Example task
Which is more: 6 or 4? How many more? Are these two groups equal?
Model response: '6 is more than 4. It is 2 more because 4 and 2 make 6. These two groups are equal — they both have 5.'
Comparing quantities and numbers to 10 confidently, using the language of comparison accurately, and beginning to order numbers based on their value.
Example task
Put these number cards in order from smallest to biggest: 7, 3, 9, 1, 5. Which number is between 3 and 7?
Model response: '1, 3, 5, 7, 9. The number 5 is between 3 and 7. 9 is the biggest and 1 is the smallest. 7 is 2 more than 5.'

Pattern Recognition in Numbers
knowledge AI FacilitatedEYMA-R-C007
The ability to identify and describe structural patterns within the numbers to 10, including: even numbers (can be split into two equal groups, no remainder), odd numbers (always one left over when split), double facts (each even number up to 10 is the double of a smaller number), and equal distribution (sharing equally into groups). These structural patterns are the earliest manifestations of multiplicative and algebraic thinking.
Teaching guidance
Use physical sharing activities — distribute objects between two teddies and observe when it works out equally (even numbers) and when there is a remainder (odd numbers). Build doubles on ten-frames using two colours and note the symmetry. Introduce the concept of 'fair sharing' as a context for equal distribution. Use bead strings, interlocking cubes in two colours, and hundred squares to make patterns visible. Avoid introducing formal notation for odd/even until KS1.
Common misconceptions
Many children at this stage associate 'even' only with specific familiar numbers (2, 4) rather than understanding it as a property defined by equal division. Some children think odd numbers are random exceptions rather than recognising the consistent 'one left over' pattern. Doubles are often treated as isolated facts rather than a family with a shared structural property.
Difficulty levels
Beginning to notice simple patterns in everyday contexts: ABAB colour patterns, day/night alternation, repeating sequences.
Example task
Continue this pattern with coloured blocks: red, blue, red, blue, red, ___
Model response: 'Blue! Because it goes red, blue, red, blue — so the next one is blue.'
Sometimes identifying and extending patterns, including patterns in numbers (odd/even, doubles) with concrete support.
Example task
Look at these numbers of objects: 2, 4, 6, 8. What is the pattern? What comes next?
Model response: 'They're going up by 2 each time! 2, 4, 6, 8... the next one is 10.' The child may verify by counting on 2 from 8.
Identifying and describing structural patterns in numbers to 10, including odd/even, doubles, and beginning to see how patterns help predict and calculate.
Example task
Sort the numbers 1-10 into two groups. What pattern do you notice? How do doubles connect to even numbers?
Model response: 'Even numbers are 2, 4, 6, 8, 10. Odd numbers are 1, 3, 5, 7, 9. Even numbers can be split into two equal groups — like 6 is 3 and 3. That's a double! So every even number is a double. Odd numbers always have one left over when you try to split them equally.'
