UNIT PLAN Grade Level: 3 Unit #: 4-2 Unit Name Measurement: Length, Volume, Mass, & Equivalencies Big Idea/Theme: Measurement is used to effectively communicate a common language of numerical information. Culminating Assessment: Rotate through the stations listed below. Record and label the following measurements as you travel through each station: Length: Measure the objects given in centimeters and inches (nearest 1/2 in.). Measure the objects given in meters and yards. Volume: Measure volume units. Complete two of the following: cups to gallons, etc. Volume: Compare liters to quarts and record the larger volume. Mass and Weight: Compare pounds. Unit Understanding(s) Student will understand that There are appropriate tools used to and students will use those tools to measure to the nearest unit. There is a relationship between the Customary and Metric units. Benchmarks can be used to make comparisons and estimates between Customary and Metric units. Thirty-six (36) inches is equivalent to a yard. Unit Essential Question(s) What are the best tools to use to measure length (volume or mass)? What is the relationship between meters and yards (kilometers and miles, liters and quarts, and kilograms and pounds)? What benchmarks can be used to measure length (liquid volume, mass, weight, meters compared to yards, kilometers compared to miles, liters to quarts, and pounds)? What is 36 inches equivalent to?
will know / will be able to Use the most appropriate measure for length, volume, and mass. Locate the nearest unit. Use other words synonymous with nearest such as closest to. Explain that measurement is an approximation in some cases. Use half inches appropriately. Use abbreviations for measurements (meters is m, pound is lb, etc.). Measure using actual tools. Read a measurement from a pictorial representation. Explain that a meter is slightly more than yard. Explain that a kilometer is a little over half a mile. Measure a mile as about one and half kilometers. Explain that a liter is slightly more than a quart. Describe the use of a kilogram as slightly more than two pounds. Identify and use standard and nonstandard measurements. Explain the concept of length, liquid volume, mass, and weight. Recognize standard units such as meters, liters, pounds, etc. Generate a common referent. Use the referent as an estimate. Compare the referent to the actual measurement. Develop strategies for making comparisons such as: when measuring weights of objects, students can hold one object in each hand, extend their arms and feel the relative downward pull of each. Recall 60 seconds = 1 minute and 36 inches = 1 yard. South Carolina Academic Standards: 3-5.2 Use appropriate tools to to the nearest unit: measuring length in meters and half inches, measuring liquid volume in fluid ounces, pints and liters; and measuring mass in grams. 3-5.3 Recognize the relationship between meters and yards, kilometers and miles, liters and quarts and kilograms and pounds. 3-5.4 Use common referents to make comparisons and estimates associated with length, liquid volume, and mass and weight: meters compared to yards, kilometers to miles, liters to quarts and pounds. 3-5.7 Recall equivalencies associated with time and length: 60 seconds = 1 minute and 36 inches = 1 yard.
