Grade 4 Measurement and Data

4.MD.1

Full Standard

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), ...

Note: Grade 4 expectations in this domain are limited to converting from a larger unit to a smaller unit (# of inches in 3 feet, # of minutes in 6 hours, etc.)

Learning Targets

  • Explain the relationship between kilometers, meters, and centimeters.
  • Explain the relationship between yards, feet, and inches.
  • Explain the relationship between pounds and ounces.
  • Explain the relationship between hours, minutes, and seconds.
  • Explain the relationship between liters and milliliters.
  • Use the relationship between units to make conversions from larger units to smaller units.
  • Use two-column tables to show relationships between units and/or make conversions from larger units to smaller units.

 

About the Math

 Students need to understand customary units and the metric system. Students see more everyday examples of customary units. They still need hands-on experiences with the metric system. To change from a greater unit to a lesser unit (i.e. foot to inches), multiply. Metric System is based on multiples of ten, when you increase the measure, multiply by ten.  Essential vocabulary for this standard includes: customary units, metric system, inch, feet, yard, ounce, ton, second, minute, hour, day, week, month, year, millimeter, centimeter, meter, gram, kilogram, milliliter, and liter.  Note: The standard is specific to the units noted above.  However, it is completely appropriate for students to work with other measurement units, but students are not expected to have mastery of these additional units.  Visit the online dictionary Links to an external site. for vocabulary support.

 

Customary and Metric Units

Customary and Metric Units
Length Weight Time Length Mass/Weight Capacity
 1 ft = 12in.
1 yd = 3 ft
1 mile = 5,280 ft		 1 lb. = 16 oz
1 ton = 2,000 lb. 		 1 minute = 60 seconds
1 hour = 60 minutes
1 day = 24 hours
1 week = 7 days
1 month = 28 to 31 days
1 month = about 4 weeks
1 year = 12 months
or 52 weeks or 365 days 		 1 meter (m) = 1,000 mm
1 meter -= 100 cm
1 meter = 10 dm
1 cm = 10 mm
1 dm = 10 cm
1 km = 1,000 m 		 1 g = 1,000 mg
1 kg = 1,000 g 		  1 l = 1,000 mL
