Solve problems involving addition and subtraction of fractions with like denominators (2, 4, and 8) by using information presented in line plots.

#### Essential Understandings

Concrete:

• Use manipulatives and models (e.g., fraction bars and fraction circles) to add or subtract fractions with like denominators (2, 4, and 8; this is an expectation of students as referenced in MAFS.4.NF.2.AP.3b).
Representation:
• Use visual representations of fractions to add or subtract.
• Using the line plot, add and subtract fractions with like denominators (1/2, 1/4, 1/8).
• Understand the following vocabulary for: line plot, sum, difference, fraction, and denominator.

 Number: MAFS.4.MD.2.AP.4a Category: Access Points Date Adopted or Revised: 06/14 Cluster: Represent and interpret data. (Supporting Cluster) :  Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

 Name Description MAFS.4.MD.2.4: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 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.
