How can you tell they’ve got it: Sets & Venn Diagrams?

If they’ve got it, you’ll see things like: List the elements in the union and intersection of two sets using a Venn diagram; Use a two-way table to enumerate all possible outcomes of two combined events; Shade regions of a Venn diagram to represent A ∪ B, A ∩ B, and A′ (complement). Or just try it together: Can your child use a table or Venn diagram to systematically list all the possible outcomes of two events — like rolling two dice — and use it to count favourable outcomes?

Sets & Venn Diagrams

Your child can list outcomes with a table or Venn diagram. They can use it to count the results of two events, like rolling two dice.

In curriculum terms

Enumerate sets and their unions and intersections systematically using tables, grids, and Venn diagrams to organise and count outcomes

Curriculum alignment

Where this fits in the official school curriculum — our best automated guess, not yet checked by a person.

This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
