Making Measurement Meaningful
Measurement is a comparison of an attribute of an item or situation with a unit that has the same attribute. Meaningful measurement and estimation of measurements depends on personal familiarity with the unit of measure being used.
Bucket Ball Around the house
Length Mass or weight Capacity Area Volume Time Temperature Angles
Students must understand the attribute they are going to measure Students must understand what a unit of measure is and how it is used to produce a measurement Students must understand the devices used to measure the attribute
Linker Cubes Linker Chains Drinking straws Paper clips Giant footprints Body comparisons: Hand Digit Height
Make it easier to focus directly on the attribute being measured. Make a good case for why standardization is important. Fun! Informal measurement gives the student an opportunity to understand the attribute being measured before introducing the standard measurement.
Estimation of measures and personal benchmarks for frequently used units help students increase their familiarity with units prevent errors in measurements aid in the meaningful use of measurement
Helps students focus on the attribute being measured and the measuring process Provides intrinsic motivation to measurement activities Helps develop familiarity with the unit of measure Emphasizes the use of approximate language, including about the measure of … Helps clarify precision of error – the most precise we can ever be is half the measured unit of measure
Find 5 items that are about the measure of 5 linker chains Find 5 items that are about the measure of a foot
Dont always start from the edge Zero on rulers vary Use a broken ruler Measure items smaller than the ruler Measure items longer than the ruler

Customary – 10 yards Metric – 10 meters = 1 dekameter Which team will reach their mark first? Cooperative Learning Groups #1 Recorder: Select and read the card. Make an estimate of the item to be measured. #2 Coach: Select and locate the right measurement tool to use. Explain the markings on measurement tool. #3 Athlete: Measure the item. Get a confirmation from team members that the measurement is accurate. #4 Equipment manager: Locate the item to measure, explain how it is used. When finished, return the item.

Kilometer Hectometer Dekameter Meter – Basic UNIT Decimeter Centimeter Millimeter
Measurement of covering Dont use formulas, allow the students to create the rules Use informal – How many deck of cards will fit onto a piece of paper? Formal – How many 1 color tiles does it take to fill the piece of paper?
Amount of space inside an object Cubic units Use wooden cubes to find fill containers.
Gallon – 128 ounces, milk jug, 4 quarts Quart – 32 ounces, eggnog, quart of milk Pint – 16 ounces, medium fountain drink Cup – 8 ounces, milk container at lunch
Kilometer – a little over ½ mile (6/10 of a mile) Hectometer – football field + one end zone Dekameter – length of a small school bus, width of your bedroom Meter – height of a door knob, baseball bat, a little more than a yard Decimeter – height of a soup can, width of your hand, length of a crayon Centimeter – width of your little fingernail, width of a paper clip Millimeter – thickness of a dime
Kiloliter – childs wading pool of water – metric ton Hectoliter – cars gas tank Dekaliter – large punch bowl, fish bowl Liter – a gulp more than a quart Deciliter – tea cup Centiliter – teaspoon of liquid medicine Milliliter – 20 drops of water
Kilogram – textbook, 5 bananas, a little over 2 pounds (2.2 lbs.) Gram – mass of a paperclip Milligram – mass of a butterflys wing
Link learning of measurement by having the students measure items at home Measurement Line-ups Cooking and Baking Scale drawings of rooms which would include measurements Informal – measure the length and width of their room by stepping it off. Build a ramp (skateboard or handicap)
Throughout the school – make measurement a focus. Points of reference A daily question with the answer given at the end of the day. How far is it from our the office to the playground? Estimate the weight of a fire truck. How much does one gallon of water weigh? How long is your principal? – Estimate, then measure. How cold is it in Hawaii today? What is the difference between our temperature and Hawaiis temperature? Metric Units and conversion The Big G and Gallon Guy The temperature of the day in Olathe
The more the students measure, the better they get at estimating and measuring! Experience measurement by measuring!
