Teaching FractionsDate: 2/2/96 at 12:11:34 From: Anonymous Subject: Re: math I'm teaching 6th grade math, multiplying fractions, and some of the students don't understand that 5 and 5/1 are the same. Any suggestions? Date: 3/24/96 at 23:8:25 From: Doctor Jodi Subject: Re: math Hi there! Here are the two approaches I can think of: - Look at division as dividing THINGS into PILES, i.e, give each child 5 counters and ask them to put them into 1 pile. Ask: how many counters are in each pile? Try this with other numbers of counters and numbers of piles to get an instinctive feel for division. (One interesting question that should come up quickly is what to do about "remainders.") - Remind your class that multiplication is the OPPOSITE of division. Just as 30/5 = 6 while 6 * 5 = 30, so is 5/1 = 5 since 5 * 1 = 5 I hope this helps! I'd be really interested in hearing other approaches you come up with. -Doctor Jodi, The Math Forum |
