Simplifying Fractions Adding/Subtracting Fractions The students have been working on all the concepts leading up to adding/subtracting fractions. Comparing fractions with unlike denominators, making equivalent fractions, simplifying fractions, and now adding/subtracting fractions Rubric Code: DBA79B By vincents Ready to use Public Rubric Subject: Math Type: Project Grade Levels: K-5

Simplifying Fractions
	Beginning 1 pts	Developing 2 pts	Accomplished 3 pts	Exemplary 4 pts
Make Equivalent Fractions	Beginning With intensive assistance, the student somewhat understands how change the fractions to equivalent fractions with the same denominators.	Developing 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.	Accomplished 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.	Exemplary 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.
Identifying Greatest Common Factor	Beginning The student does not know the process of finding GCF of a given fraction without teacher assistance.	Developing With some assistance the student somewhat understands the process of finding the GCF of a fraction.	Accomplished With minimal assistance the student somewhat understands the process of finding the GCF of a given fraction.	Exemplary The student fully understands the process of finding the GCF of a given fraction.
Simplify Fractions	Beginning The student does not know or does not simplify fractions without assistance.	Developing With some assistance the student may somewhat understand to list the factors of the numerator and/or denominator. An attempt is made to find the common factors and divide the numerator/denominator by the common factors, but the factors may not be in simplest form.	Accomplished With minimal assistance the student is able to list the greatest common factors of the numerator and denominator and then dividing the numerator and denominator by the GCF to come up with the most simplified version of the fraction.	Exemplary The student is able to list the greatest common factors of the numerator and denominator and then dividing the numerator and denominator by the GCF to come up with the most simplified version of the fraction.
