Yes, but in your first sentence you mean "coaching", not "couching. "Coach" means "to teach" or "to train"

Firstly I think the word you want is coaching not couching. Although you sentences are not really wrong, you would not use this kind of language with a child. The sort of thing you might say: Turn it round, turn it over, try it the other way round - that kind of thing. It depends a bit on the kind of puzzle.
