• CHAPTER 12: RELATIVE SIZES OF MEASUREMENTS

    In Chapter 12 students will:  
    • solve problems involving measurement
    • solve problems with conversion of measurement
    • represent and interpret data

    Vocabulary:
    • millimeter - a metric unit used to measure length:  1,000mm = 1m
    • decimeter - a metric unit for measuring length or distance:  10 dm = 1 m
    • ounce - a customary unit to measure weight:         16 oz = 1 lb
    • pound - a customary unit to measure weight:          1 lb = 16 oz
    • ton - a customary unit used to measure weight:      1 ton = 2,000 lb
    • fluid ounce - the smallest customary unit for measuring liquid volume: 
      8 fl oz = 1 c
    • cup - a customary unit to measure liquid volume: 2c = 1 pt; 16c = 1gal
    • pint - a customary unit to measure liquid volume: 1pt = 2c; 8pt = 1gal
    • quart - a customary unit to measure liquid volume: 1qt = 2pt; 4qt = 1gal
    • half gallon - a customary unit to measure liquid volume: 2qt = 1/2gal
    • gallon - a customary unit to measure liquid volume: 1gal = 4qt
    • milliliter - a metric unit to measure liquid volume: 1,000 mL = 1 liter
    • second - a unit of time: 60 seconds = 1 minute;      60 min = 1 hr
    • line plot - a graph that shows the frequency of data along a number line

    Chapter 12 Standards:  Measurement and Data (4.MD)
    Measurement and Data: Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

    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.(CC.4.MD.1)

    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. (CC.4.MD.2)

    Represent and interpret data.

    4. 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.(CC.4.MD.4)
