[quote=Anonymous][quote=Anonymous]If it were a choice between number sense OR speed and accuracy in doing a problem by hand (which it isn't), I'd pick number sense. You can do a calculation quickly and accurately using a calculator, and calculators are ubiquitous. But a calculator won't tell you whether the answer makes sense.[/quote]

I grew up with calculators and I don't enjoy mental calculations, but I still think settling on and practicing an algorithm is a necessary stage of development.  My DC runs into keying issues with calculators, too.  Some are carelessness, some are order of operations and distributive law. Even with a multiline calculator, there are plenty of ways to type something that doesn't mean what's intended.  (And, there's still things to make sense of like, when your phone calculator is vertical 3 + 4 * 5 is different than when it's horizontal.)  Anyway for my DC it's like years of wishy washy, show me how [i]you[/i] do it, have muddied the fact that math is deterministic.  But my only point is, I work with my kids all the time and I see quirks in their background knowledge, there's no way this is unique to them.[/quote]
