21. Select and use an appropriate unit of measurement for a given attribute (length, mass, liquid volume, time) within one system of units: metric - km, m, cm; kg, g, l, ml; customary - lb, oz; time - hr, min, sec.

a. Within one system of units, express measurements of a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table.

Evidence Of Student Attainment:
Students:
  • Use the relationships between measurement units to express larger units of measure in smaller units.

    • Example: Convert 2 feet to 24 inches, 2 hours to 120 minutes, but not smaller units to larger units for instance, converting 150 feet to 50 yards.
  • Use a two-column table to show relationships between larger units and smaller units and/or make conversions.
Teacher Vocabulary:
  • Appropriate unit of measure

Knowledge:
Students know:
  • units of measures for given attributes vary in size and are related by multiplicative comparison.
Skills:
Students are able to:
  • Select and use appropriate units of measure for a given attribute.
  • Convert larger units of measure to smaller units of measure within the same measurement system.
  • Record measurement equivalents in a two-column table.
Understanding:
Students understand that:
  • There is an appropriate unit of customary measurement and metric measurement for a given attribute.
  • Multiplicative relationships exist between customary units of length, mass, liquid volume, and time.
  • Multiplicative relationships exist between metric units of length, mass, liquid volume.

Essential Skills:
Learning Objectives:
M.4.21.1: Define conversion.
M.4.21.2: Define length, kilometers, meters and centimeters.
M.4.21.3: Define weight, kilograms, grams, pounds, ounces, liters and milliliters.
M.4.21.4: Define hour, minute, second.
M.4.21.5: Measure and estimate liquid volumes and masses of objects using standard units of grams, kilograms, and liters.
M.4.21.6: Identify standard units of measurement equivalents.
Examples: 60 minutes equals 1 hour, 16 ounces equals 1 pound.
M.4.21.7: Match measurement units to abbreviations.
Examples: kilometers (km), meters (m), centimeters (cm), kilograms (kg), grams (g), pounds (lb), ounces (oz), liters (l), milliliters (ml)

Prior Knowledge Skills:
  • Define liquid volume, mass, grams, kilograms, and liters.
  • Recognize how the standard units of measure compare to one another.
  • Identify key terms for word problems.
    Examples: Difference, altogether, in all, between.
  • Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
  • Recall basic addition, subtraction, multiplication, and division facts.
  • Describe measurable attributes of objects such as length or weight. Describe several measurable attributes of a single object.
  • Compare equivalent units of time using hours and minutes.
    Examples: 60 minutes = one hour, 30 minutes = one half of an hour.
  • Recognize key vocabulary and/or phrases associated with time.
    Examples: Quarter 'til = 15 minutes before; half past the hour = 30 minutes after the hour.
  • Compare the lengths of time to complete everyday activities
    Examples: Brushing your teeth = about 2 minutes; riding the bus = about 20 minutes.
  • Tell and write time in hours and half-hours using analog and digital clocks.
  • Recognize hour, minute, and second hands on an analog clock.
  • Count by 5's to 60.
  • Determine the monetary value of a set of like and unlike bills.
  • Determine the monetary value of a set of like and unlike coins.
  • Apply addition and subtraction strategies.
  • Understand key words in addition and subtraction word problems involving money.
    Examples: adding to, taking from, putting together, taking apart, sum, difference, all together, how much more, how much is left, in all, cents, dollar, change, paid, total.
  • Count forward from a given number by ones, fives, tens, and twenty-fives.
  • Identify coins and bills and their value.
  • Identify symbols for dollar ($), cent (¢).
  • Identify coins by name including penny, nickel, dime and quarter.
  • Sort pennies, nickels, dimes, and quarters.
  • Count 10 objects.
    Examples: pennies and dollar bills
  • Tell and write time in hours and half-hours using analog and digital clocks.
  • Recognize vocabulary terms related to time measurements.
    Examples: minute, hour, half hour, o'clock, morning, evening, a.m., p.m.
  • Illustrate time to hour and half hour.
    Example: Given the time 3:00, illustrate long hand and short hand positions on a clock.
  • Identify the short hand as the hour hand, and the long hand as the minute hand on an analog clock.
  • Identify the first number as the hour, and the numbers after the colon as the minutes on a digital clock.
  • Write numerals 0 to 59.
  • Recognize numerals 0 to 59.
  • Count to 60 by fives.
  • Distinguish between analog and digital clocks.
  • Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
