Ralph, I have absolutely no experience in sixth grade, so I can't tell anybody how to teach them. I would make one small suggestion for elementary teachers to consider, but it might be best a little earlier than sixth grade. My wish is that for the first month or more that students were introduced to fractions the teachers and texts would avoid the use of the typical a/b notation. It seems to confuse from day one and never get un-confused. I think if I asked any group of third graders what happens when I add four bunnies to three bunnies, they would universally proclaim seven bunnies as the obvious response. And I know, BEFORE they are introduced to the notation, if you asked about four ninths plus three ninths, they may ask what the heck a ninth is, but would still declare the answer to be seven of 'em, whatever they are. BUT... We introduce the notation 4/9 + 3/9 and they can say the words, but the rhythm is lost. They want to Add ALL THE numbers they see... because they don't yet see the nines as names... and they may actually be too young to see it yet. I don't know how hard it would be to get them to see that 1 half was the same as 2 fourths or 4 eighths, but I would love to see someone try... this seems to be the first place where students decide they will give up trying to reason out mathematical ideas and tell the teacher whatever they think she/he wants to hear. Later (maybe eighth grade) we could introduce them with this really "cool" way of writing out the fractions for the '''ths. Maybe it would never work, I still struggle with language with advanced high school seniors, so I can't predict what would happen, but the way we do it now seems NOT to work. Maybe the sixth grade teachers could explain to me where my idea would go wrong. I know there is not an easy answer, but would love to think there IS and answer. -Pat Ballew, for the T2T service Thanks for visiting our on-line community.
