It's the sort of thing that makes teaching hard, too.
Multiple approaches, coupled with plenty of practice, really does work better for more students in the long run, though. We really want to force them to think about what they're doing, and they won't do that if they can just coast along by memorizing patterns.
(Note: However, if your kid is doing Everyday Math - which it sounds like from the emphasis on lattice multiplication! - that curriculum works well when the teacher knows the material backwards and forwards and the class spends a couple of hours a day on it. Neither of these things is guaranteed in real life, so.... If you have the whole of summer opening up in front of you and don't mind doing a couple hours of school a day, I recommend either Singapore Math if you're willing to follow the home instructor's guide and not just plow through the workbooks, and Math Mammoth if you're not.)
