Sorting Data into Categories
PROCEDURALOrganise and represent data with up to three categories by counting objects in each category and sorting categories by quantity
Mastery Evidence
- Sort a set of objects into 2-3 given categories and count each group
- Create a simple table or list showing category names and counts
- Order categories from most to fewest or fewest to most
Assessment Prompt
“Can [child] look at a collection of objects — like different coloured counters — sort them into up to three groups, count each group, and organise the results into a simple chart?”
Curriculum Standards3 alignments

- 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'
- Pictograms and tally charts (age 6+) hard
Organising and representing data requires data, tally, frequency, and category vocabulary
- Sorting into categories hard
Organising data in categories builds on classifying and counting objects in categories
- Comparing groups: more or fewer soft
Sorting categories by count benefits from ability to compare quantities
- Counting objects to 20 soft
Counting a set helps when comparing groups, but younger children (GB age 4) can compare using matching without formal counting to 20
