4.MD Measurement and Data

  • 4.MD.A Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

  • 4.MD.B Represent and interpret data.

  • 4.MD.C Geometric measurement: understand concepts of angle and measure angles.

    • 4.MD.C.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

      • 4.MD.C.5a 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 two rays intersect the circle.

      • 4.MD.C.5b 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.5c An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

    • 4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

    • 4.MD.C.7 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 letter for the unknown angle measure.

  • 4.MD.D Relate area to operations of multiplication and addition.

    • 4.MD.D.8 Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real-world problems.
