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!
