# What grade level is multiplying fractions?

## Recommended Posts

Wondering when it is normally taught.

California has it on the 5th grade standards.

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.

Typically in 6th grade. Maybe earlier in some curriculums.

We're doing it in 5th.

Common Core has it in 5th grade.

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.

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.

I would have guessed 5th. Can't imagine why not in 4th though.

I was thinking around 4th grade. I am pretty sure my daughter in public school learned it way before 5th grade.

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.

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?

MM has 1/2 x 100 in CH 2 of 3A in the into to multiplication chapter.

Me too. My son learned it n 3rd and 4th, but i dont recall if it was through his main curriculum or a supplement.

Simple fractions- late 3rd grade, mastered by 5th.

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.

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.
