Please help me correctly answer my son's 3rd grade math question.

The final answer might be given as the list of numbers, or it might be given as “the ones that end in 0”, or “the multiples of 10”. Saying “the multiples of 10” probably shows a greater understanding of the concept, but the way the question is worded, any of those should be acceptable. Hopefully her teacher isn’t just looking for the One True Answer that the answer key says is right.

Well, we looked at it like this: Multiples of five end in 5 or 0. 0 also ends numbers that can be divided by 2.

Once my son got that, he figured out 10, 20, 30…

Problem solved.
