Look at this grid, which is also called a Carroll diagram.
A Carroll diagram can help us sort information into groups.
In this diagram, we can sort numbers to determine whether they are odd or even, and whether these odd and even numbers are multiples of 5, 7 or both 5 and 7.
The number 21 would go in section E because it is an odd multiple of 7.
The number 30 would go in section A because it is an even multiple of 5.
The number 70 would go in section C because it is an even multiple of both 5 and 7.
Does that make sense!
Let's get started!
