Sets & Venn Diagrams
Enumerate sets and their unions and intersections systematically using tables, grids, and Venn diagrams to organise and count outcomes
Lesson
Set out your lesson
“Sets & Venn Diagrams means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Two overlapping circles drawn on paper
- Counter tokens or number cards
Extra for the adult
Worked example. 6 is even and a multiple of 3, so it goes in the overlap.
Optional challenge. For Sets & Venn Diagrams, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Sets & Venn Diagrams, not mastery.

Check understanding
- 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)
“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?”
