Are the following statements always true, sometimes true or never true?

You could cut out the statement cards and arrange them in this grid.

When you multiply by an odd number the answer is odd	When you multiply by an even number the answer is even	Doubling a number results in an even number
When you multiply a number by itself the answer is even	The sum of four even numbers is divisible by four	Adding three consecutive numbers results in an even number

Can you find examples or counter-examples for each one?

For the “sometimes” cards, can you explain when they are true? Or rewrite them so that they are always true or never true?
