Adding Fractions with Like Denominators Adding Fractions with Like Denominators CCSS.MATH.CONTENT.4.NF.B.3.B Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

Adding/Subtracting Fractions
	Limited Progress Towards Standard 1 pts	Progressing Towards the Standard 2 pts	Meets the Standard (proficient) 3 pts	Exceeds the Standard 4 pts
Make models for Fractions	Limited Progress Towards Standard With intensive assistance, the student somewhat understands how show different representation for fractions.	Progressing Towards the Standard With some assistance, the student somewhat understands how to show different representation for fractions.	Meets the Standard (proficient) With minimal assistance the student is able to make representations for fractions.	Exceeds the Standard The student is able to make models to show fractions written in different forms.
Add the Fraction	Limited Progress Towards Standard The student does not know how to correctly add or subtract the fractions without assistance.	Progressing Towards the Standard With some assistance the student somewhat understands how to add and subtract fractions with like denominators.	Meets the Standard (proficient) With minimal assistance the student somewhat understands how to add or subtract fractions with like denominators.	Exceeds the Standard The student fully understands how to add the new numerators together, while the denominator stays the same.
Recipe	Limited Progress Towards Standard Is dependent on teacher to create the recipe. Is emerging in task.	Progressing Towards the Standard Has two discrepancies in the recipe. Task is developing	Meets the Standard (proficient) Has one discrepancy. Task is almost complete	Exceeds the Standard Has no discrepancies. Mastered task.
