Look at this grid (Carroll diagram)
A Carroll diagram can help us sort information into groups
In this diagram, we can sort numbers that are either 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 5 and 7.
