Adding/Subtracting Fractions
	Novice 1 pts	Apprentice 2 pts	Proficient 3 pts	Distinguished 4 pts
Make Equivalent Fractions	Novice With intensive assistance, the student somewhat understands how change the fractions to equivalent fractions with the same denominators.	Apprentice With some assistance, the student somewhat understands the concept of making equivalent fraction, but their understanding is not complete. They make may the new denominator the LCM but is not sure about how to get the new numerator.	Proficient With minimal assistance the student is able to make equivalent fractions from making the LCM of the unlike denominators the new denominators and then multiples the numerator by the same number they multiplied their old denominator by to get their new denominator.	Distinguished The student is able to make equivalent fractions from making the LCM of the unlike denominators the new denominators and then multiples the numerator by the same number they multiplied their old denominator by to get their new denominator.
Add/Subtract the Fraction	Novice The student does not know how to correctly add or subtract the fractions with unlike denominators without assistance.	Apprentice With some assistance the student somewhat understands that when the denominator is different, they need to make equivalent fractions. They make an attempt to find the new numerators/denominators and adds or subtracts only the numerator.	Proficient With minimal assistance the student somewhat understands that when the denominator is different, they need to make equivalent fractions. They make an attempt to find the new numerators/denominators and adds or subtracts only the numerator.	Distinguished The student fully understands to add the new numerators together, while the denominator stays the same, as well as adding the whole numbers.
Multiply the Fractions	Novice The student does not know how to correctly multiply the fractions with unlike denominators without assistance.	Apprentice With some assistance the student somewhat understands a fraction a/b as a multiple of 1/b.	Proficient With minimal assistance the student somewhat understands With some assistance the student somewhat understands a fraction a/b as a multiple of 1/b.	Distinguished The student fully understands a fraction a/b as a multiple of 1/b.
