Measurement and Data
NC.4.MD.1- Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two- column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36)
​
NC.4.MD.2- 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.
​
NC.4.MD.3- Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, nd the width of a rectangular room given the area of the ooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
​
NC.4.MD.4- Represent and interpret data using whole numbers.
-
Collect data by asking a question that yields numerical data.
-
Make a representation of data and interpret data in a frequency table, scaled bar graph, and/or line plot.
-
Determine whether a survey question will yield categorical or numerical data.
