Integrated Task
Standards:
4NF.B.3A: Understand addition and subtraction of fractions as joining and separating parts
referring to the same whole.
4NF.B.3B: 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.
4NF.B.3C: Add and subtract mixed numbers with like denominators, e.g., by replacing each
mixed number with an equivalent fraction, and/or by using properties of operations and the
relationship between addition and subtraction.
4NF.B.3D: Solve word problems involving addition and subtraction of fractions referring to the
same whole and having like denominators, e.g., by using visual fraction models and equations
to represent the problem.
Practice Standards: 1, 2, 3, 4, 6, 7, 8

Part A.
When the competition was over, the judges added up all the lengths of fish. Who had the
highest total length? Who had the least?
Part B.
Sam said he won because he had the highest denominator in his total score. Is Sam correct?
Why or why not?
Part C.
David did not get a third fish. What size of a fish would have helped him tie with the first place
winner? Show your reasoning.
