Max Maths, Year 3, Try it, Sorting according to two criteria using Carroll diagrams

In this engaging activity from Max Maths for Year 3, students are encouraged to explore number properties by sorting the numbers 1 to 20 into a Carroll diagram. The diagram is divided into sets to categorize the numbers based on two criteria: being a multiple of 3 and being an even number. On one side of the diagram, students will place numbers that are multiples of 3, and on the other side, they will place numbers that are not. Additionally, they will sort these numbers into whether they are even or not, allowing for a clear visual representation of the intersection between these two sets.

After placing the numbers into the Carroll diagram, students are prompted with questions to further their understanding. They must identify which numbers are both even and a multiple of 3. This leads to an exploration of additional numbers beyond the initial range that also fit these criteria. Finally, students are encouraged to observe a pattern among the numbers that are both even and multiples of 3, leading to the discovery that these numbers are all multiples of a certain number. This activity not only reinforces knowledge of multiplication and even numbers but also develops critical thinking and pattern recognition skills. For further practice and reinforcement, students are directed to workbook pages 108 to 111.
