UNIT 7: +/- Fractions Practice-Test
Name: ______________________
MAFS. 4.NF.2.3: Understand a fraction a/b with a > 1 as a sum of fractions 1/b
a. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
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.
c. 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.
d. 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
Depth of knowledge: 2
MAFS.4.NF.3.5: Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective
denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100. Cognitive Complexity: Level 1: Recall
MAFS.MD.2.4: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/8). Solve problems involving addition and subtraction of fractions
by using information presented in line plots.For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an
insect collection
