Editable PowerPoint slides on Venn diagrams for Year/Grade 7 to 10. Each deck builds from listing sets and reading two-circle diagrams through union, intersection and complement notation, on to three-set problems and probability from a Venn diagram — with worked examples, guided practice, and exit-ticket questions built in.

Two-circle and three-circle diagrams drawn step by step, with shaded regions on their own slides for union (A ∪ B), intersection (A ∩ B), and complement (A'). Animated reveals let you pause, ask the class to predict the shaded region, then reveal it together.


Real-context tasks ask students to sort a list of items into the right region — sports played, languages spoken, favourite subjects — then read off how many sit in the intersection. Decks then extend into set-builder notation and probability from a Venn diagram.
Quick-check questions move from "shade A ∩ B" through "find P(A or B) from this diagram" to the kind of multi-step worded problem students see in end-of-topic tests. Answers and full working sit on the teacher slide.

Guided practice keeps one move per slide: first sort the data into the diagram, then write the union and intersection in set notation, then compute the probability. Students at different paces can work the same deck without needing separate handouts.
Each region — A only, B only, intersection, complement — is colour-coded on a slide of its own, so students lock in what each part of the diagram means before they're asked to use the notation. Worked examples build from two-set to three-set diagrams at a deliberate pace.
End-of-topic check slides cover reading a Venn diagram, drawing one from a worded scenario, writing union and intersection in set notation, and finding probabilities like P(A ∩ B) and P(A | B). Use them as exit tickets or convert them into a printable check-for-understanding in two clicks.

Reading and Shading Venn Diagrams
The opening slides define a set, introduce two-circle and three-circle Venn diagrams, and walk students through naming each region — A only, B only, the intersection, and the area outside both circles. Worked examples shade union (A ∪ B), intersection (A ∩ B), and complement (A'), one region per slide, so the class can predict the shading before it appears. Checkpoint questions ask students to shade a region on a printed diagram and write down what it represents in plain language before any notation is introduced.
Set Notation, Three-Set Diagrams and Worded Problems
The middle of the deck moves from shading to writing. Students learn the symbols for union, intersection, complement, subset and the universal set, then write the same statement in three forms — a sentence, a shaded diagram, and set-builder notation. Worked examples scale from two sets (students who play soccer and students who play tennis) up to three-set diagrams with seven regions, including the trickier centre region that sits in all three sets. Practice questions ask students to sort a worded scenario into a diagram, then read off how many sit in the intersection or the complement.
Probability From a Venn Diagram
The closing section connects Venn diagrams to probability. Slides build P(A), P(A ∪ B), P(A ∩ B), and conditional probability P(A | B) directly off the diagram by counting outcomes in each region, then check the answer against the addition rule P(A ∪ B) = P(A) + P(B) − P(A ∩ B). Worked examples use survey-style data — students who play a sport, students who play an instrument, students who do both — so the algebra of probability lands against something students can picture. The final slide separates mutually exclusive events from overlapping events with a side-by-side diagram, so students do not confuse the two when the unit ends.
