Fractions by grade level

Can anyone help me with the progression of what you teach for fractions, preferably by grade level, up through the end of 5th grade? I know the grade-level aspect may vary from state to state, but a rough estimate of what gets taught when, and in what order would be helpful.

Here's what I have come up with, in what seems to be a logical order, with a guess as to when it's introduced.


Introduction of concept of fractions -- 1st / 2nd
Fraction terminology - 1st /2nd
Comparing fractions ( greater than, less than, etc. ) -- 3rd
Adding and subtracting fractions with the same denominator -- 3rd /4th
Converting improper fractions into mixed numerals and vice versa - 3rd /4th
Reducing fractions -- 4th
Finding the LCD for two fractions - 4th
Adding and subtracting fractions with different denominators - 4th /5th
Converting fractions into percents and vice versa - 5th / 6th
Multiplying and dividing fractions - 5th / 6th


Did I miss anything? ( Don't worry, BTW. I'm not an elementary teacher, and this is for my use with my own kids. )


Thanks so much for your help!

That looks pretty good to me! I would start introducing vocabulary day one in first grade. They need to be familiar. I never call the numerator the "top number" etc. It looks like at my school we are about a year behind. We don't multiply and divide fractions in 5th.

This looks good- Harcourt has kids converting fractions to mixed numbers and adding/subtracting with like denominator in 3rd. We don't convert fractions to percents until 5th-6th.

Thanks for the input, trish and becky. As I said, I was just guesstimating when each concept is taught, so I doubt your school is behind, Becky. I may have just jumped the gun on that last one.

Would still appreciate input from anyone else who may have something to add or change.
