Grade 4: Measurement and Data

Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

NY-4.MD.1

Fully covered
Know relative sizes of measurement units: ft., in.; km, m, cm. Know the conversion factor and use it to convert measurements in a larger unit in terms of a smaller unit: ft., in.; km, m, cm; hr., min., sec. Given the conversion factor, convert all other measurements within a single system of measurement from a larger unit to a smaller unit. Record measurement equivalents in a two-column table.

NY-4.MD.2

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money.

NY-4.MD.2.a

Mostly covered
Solve problems involving fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit.

NY-4.MD.2.b

Partially covered
Represent measurement quantities using diagrams that feature a measurement scale, such as number lines.

NY-4.MD.3

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

Represent and interpret data.

NY-4.MD.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.
(Content unavailable)

Geometric measurement: understand concepts of angle and measure angles.

NY-4.MD.5

Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.

NY-4.MD.5.a

Fully covered
Recognize 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.

NY-4.MD.5.b

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

NY-4.MD.6

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

NY-4.MD.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.
