courtney.byrum Posted September 25, 2012 Share Posted September 25, 2012 Through k12 I believe the first time was 5th grade math. I'll double check the 4th grade book we still have and see but I think that was just adding/subtracting fractions. Upon checking the 4th grade book - there is multiplication and division but only with a fraction times a whole number - fraction times fraction isn't until 5th.

Tammi K Posted September 25, 2012 Share Posted September 25, 2012 Typically in 6th grade. Maybe earlier in some curriculums. Quote Link to comment Share on other sites More sharing options...

FaithManor Posted September 25, 2012 Share Posted September 25, 2012 Late 5th grade in our local school district. It's in the 5A book of Singapore Math US ED, however I think it's 4th grade in Singapore and the concept is played around with visually, if memory serves, at the end of the 4B book. I think it is also lightly introduced towards the end of the 4th grade book in Rod and Staff math. Faith Quote Link to comment Share on other sites More sharing options...
Mom22ns Posted September 25, 2012 Share Posted September 25, 2012 It was 5th here. There was a fairly large fractions unit at the end of fourth, but they didn't make it to multiplying until early 5th. Quote Link to comment Share on other sites More sharing options...

Pamela H in Texas Posted September 25, 2012 Share Posted September 25, 2012 I would have guessed 5th. Can't imagine why not in 4th though. Quote Link to comment Share on other sites More sharing options...
gingersmom Posted September 25, 2012 Share Posted September 25, 2012 I was thinking around 4th grade. I am pretty sure my daughter in public school learned it way before 5th grade. Quote Link to comment Share on other sites More sharing options...
justasque Posted September 25, 2012 Share Posted September 25, 2012 (edited) Possibly "foreshadowing" in 4th. (Brief intro, without full variations, no intro of division of fractions.) Intro in 5th. More expansive practice in 6th, with more word problems, etc. Mastered in 7th, with it as one step in more complex, multi-step problems, and (after being reviewed briefly) used throughout the book rather than focused on in just one chapter. Most math topics, in most texts, seem to be covered in this three-year, intro/practice/master, way.

Farrar Posted September 25, 2012 Share Posted September 25, 2012 This is surprising to me. Because it seems late? Or early? Miquon has multiplying fractions and whole numbers in really simple ways starting in first grade. But that's weird. I think MM has that - also the really simple stuff like 1/2 X 100 or 1/3 x 9 in the third grade fractions section? Quote Link to comment Share on other sites More sharing options...

Halcyon Posted September 25, 2012 Share Posted September 25, 2012 This is surprising to me. Me too. My son learned it n 3rd and 4th, but i dont recall if it was through his main curriculum or a supplement. Quote Link to comment Share on other sites More sharing options...
QueenCat Posted September 25, 2012 Share Posted September 25, 2012 Simple fractions- late 3rd grade, mastered by 5th. Quote Link to comment Share on other sites More sharing options...
Dinsfamily Posted September 25, 2012 Share Posted September 25, 2012 By a whole number: 3rd Two fractions: 5th I do think our ps doesn't do it until 4th and 6th (or later), respectively. They don't introduce multiplication until 3rd. This is surprising to me. why? Too early or too late. Quote Link to comment Share on other sites More sharing options...
NanceXToo Posted September 26, 2012 Share Posted September 26, 2012 We're doing it in 6th with Teaching Textbooks. It did plenty of other stuff with fractions in 5th but multiplying them is in 6th. Quote Link to comment Share on other sites More sharing options...
