What the test measures

Add and Subtract Fractions skills

  1. Understand a fraction as the sum of unit fractions with the same denominator and use this understanding to add and subtract fractions.

  2. Solve real-world problems by adding and subtracting fractions with like denominators, including problems with fractional data presented on a line plot.

  3. Standards: 4.NF.3, 4.NF.3.a, 4.NF.3.b, 4.NF.3.c, 4.NF.3.d, 4.MD.4

Standards basis

Montana PK-12 Mathematics Content Standards / Common Core State Standards for Mathematics (CCSS-M)-aligned Montana standards — Montana

How the MAST reports it

Montana’s MAST is a state-specific through-year assessment built by New Meridian and aligned to Montana’s academic content standards, not a Smarter Balanced-style claims/targets framework. The math blueprints organize content into grade-level strands/testlets that map directly to CCSS-M-derived Montana standards.

Blueprint & weighting

The blueprint publishes a through-year design of 12 strands/testlets per grade, with 1 strand per testlet, 2 reporting attributes per strand, and 9–13 items per testlet. It also specifies approximate item-type and DOK distributions, but does not publish percentage weighting by domain in the captured blueprint text.

A line plot of pencil lengths (in inches) shows two pencils at 14\tfrac{1}{4}, three at 24\tfrac{2}{4}, and one at 34\tfrac{3}{4}. How many pencils were measured?

Add the marks: 2+3+1=62 + 3 + 1 = 6.

Practice playeasy

A line plot shows value 2: 4 X's, value 3: 2 X's, value 4: 3 X's. How many X's are at value 2 and value 4 combined?

Add the X's at those two values: 4+3=74 + 3 = 7.
