Mathematics – Measurement and Data

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

• 4.MD 1.0 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.

• 4.MD 2.0 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 lien diagrams that feature a measurement scale.
