Sorting Master

Help Detective Venn solve sorting mysteries using overlapping circles! Master Venn diagrams to organise data like a pro!

Good evening, young detective! I'm Detective Venn, and I solve mysteries by sorting clues into overlapping circles! There's been a mix-up at the Number Station. Numbers have been jumbled together and we need to sort them out using my favourite tool, the Venn diagram. Are you ready to crack the case? Let's go!

Meet Detective Venn

A Venn diagram uses overlapping circles to show how groups of things are related. The overlap in the middle, called the intersection, shows items that belong to both groups. The union means everything inside the circles combined.

What is a Venn Diagram?

Let's sort the factors of 12 and factors of 18 into a Venn diagram. The common factors 1, 2, 3, and 6 go in the intersection. 4 and 12 go in the left circle only, and 9 and 18 go in the right circle only. The highest common factor is the largest number in the intersection, which is 6!

Cracking the Case: Factors

Time to test your detective skills! You'll get 3 questions about Venn diagrams. Think carefully about which items go where. Good luck, detective!

Quiz Round 1

A real detective can read data from a Venn diagram. Be careful not to count the intersection twice! The total with a cat is cat only plus both. And always check your total: all sections must add up to the total number surveyed.

Reading Data from Venn Diagrams

This is the final investigation! Use the pets Venn diagram to answer 4 questions. Remember: don't count the intersection twice, and all the sections must add up to the total. You can do this, detective!

The Final Investigation — Round 2

Brilliant detective work! You've learnt that Venn diagrams use overlapping circles to sort items into groups. The intersection shows items in both sets. The union is everything inside the circles. Always check your total adds up. You're now a certified Venn Diagram Detective! Keep practising and you'll ace your 11 plus exams!
