# Grade 4: Measurement and Data

### 4.MD.A.2

Mostly covered
Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

### 4.MD.A.3

Fully covered
Apply the area and perimeter formulas for rectangles in real world and mathematical problems.

### 4.MD.B.4

Fully covered
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.

#### 4.MD.C.5.a

Fully covered
An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

#### 4.MD.C.5.b

Fully covered
An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

### 4.MD.C.6

Fully covered
Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

### 4.MD.C.7

Mostly covered
Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
