# Max Maths, Year 4, Learn together, Venn diagrams (1)

In a Year 4 Max Maths lesson, students are introduced to the concept of Venn diagrams as a visual tool for sorting numbers based on given criteria. The lesson focuses on a specific Venn diagram with two overlapping circles. The left circle is designated for numbers that belong to the 5 times table, while the right circle is for odd numbers. The overlapping section, or the intersection, is reserved for numbers that satisfy both conditions: they are odd and part of the 5 times table. Numbers that do not fit into either category are placed outside the two circles. This exercise helps children to categorise the numbers 5, 8, 10, 25, and 31 accordingly, reinforcing their understanding of multiplication tables and odd numbers.

Through this activity, students learn to analyse and classify numbers efficiently. For example, the number 5 is both an odd number and in the 5 times table, so it would be placed in the intersection of the two circles. The number 25, also fitting both criteria, joins 5 in the intersection. On the other hand, numbers like 8 and 10, which are neither odd nor in the 5 times table, would be positioned outside the circles. The number 31, being odd but not in the 5 times table, would be placed in the circle for odd numbers only. This visual sorting exercise enhances students' number recognition skills and their ability to identify patterns and relationships between different sets of numbers.
