Re: [Phys-l] Old News That Stays News

From:"Thus, when a parent is asked to multiply 88 by 5, we'll do it with pen andpaper, multiplying 8 by 5 and carrying over the 4, etc. But a child todaymight reason that 5 is half of 10, and 88 times 10 is 880, so 88 times 5 ishalf of that, 440 -- poof, no pen, no paper."How do they teach multiplication of 88 by, say, 7?----- Original Message -----From: "John Denker" <>To: "Forum for Physics Educators" <>Sent: Sunday, July 20, 2008 10:03 AMSubject: Re: [Phys-l] Old News That Stays News>
