I tend to give my kids (3 and 5) verbal logic puzzles to get their conditional down. Something along the lines of "A cat has a tail and four legs and a dog has a tail and four legs, so a cat must be a dog". It normally ends with them pointing out why they are different... Just as an example but there are all kinds of everyday occurrences that can be used to initiate a logic puzzle.
