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:

HandDigit 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 unitsprevent errors in measurementsaid 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

Don’t 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

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.

Link learning of measurement by having the students measure items at homeMeasurement Line-upsCooking and BakingScale 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 Hawaii’s 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!
