Spotting mathematical patterns
METANotice simple patterns and structures: spot that changing order doesn't change the total, and recognise how numbers relate to each other
Mastery Evidence
- Notice that 3 + 2 gives the same answer as 2 + 3 (early commutativity)
- Recognise that teen numbers are 'ten and some more' (e.g. 14 is 10 and 4)
- Spot a pattern in a sequence of objects or numbers and predict what comes next
Assessment Prompt
“Has [child] noticed that adding numbers in a different order gives the same answer — like 3 + 5 and 5 + 3 both equal 8 — and can they explain why that makes sense?”

- Addition as combining or putting together two soft
Noticing commutativity of addition exercises spotting structural patterns
- How Many in Total? hard
Understanding addition as combining groups requires knowing numbers represent quantities (cardinality)
- One-to-one counting hard
Cardinality principle builds on one-to-one correspondence — you must count correctly to know the last number tells 'how many'
- How Many in Total? hard
Understanding tens-and-ones composition requires cardinality — knowing numbers represent quantities
- One-to-one counting hard
Cardinality principle builds on one-to-one correspondence — you must count correctly to know the last number tells 'how many'
- Reading and writing numbers to 20 hard
Composing/decomposing teen numbers requires reading and writing those numerals
- How Many in Total? hard
Reading/writing numerals 0–20 requires understanding that numerals represent quantities (cardinality)
- One-to-one counting hard
Cardinality principle builds on one-to-one correspondence — you must count correctly to know the last number tells 'how many'
- Writing digits 0-9 hard
Writing numerals requires the motor skill of forming digits 0-9 (taught in English handwriting)
