MeasurementGoal 2:
2.01: Estimate the measure of an object in one system given the measure
of that object in another system.

Vocabulary Power• A unit is a quantity used as a measure• Customary units are used in the USA• Metric units are used all over the world.• Standard units include both customary and metric
units• Nonstandard units are……..( You need to define)• The precision of a measurement is related to the
unit of measure you choose. The smaller the unit, the more precise the measurement will be.

Customary Length
• Length- the longest extent of anything as measured from end to end.
Customary Units of Length12 inches (in.) = 1 foot (ft)
3 feet= 1 yard (yd)5,280 feet= 1 mile (mi)
1,760 yards= 1 mile
Can you create a saying to help us remember these figures?

Nonstandard units of length
Thinking OUTSIDE the box: Why doesn’t everyone have the same answers?Are you correct and your classmates wrong?

Explain what you know about a ruler.Be sure to include:
• What is it?• What does it measure?
• What do all those marks mean?• When do you use it ?
![Page 8: Measurement Goal 2: 2.01: Estimate the measure of an object in one system given the measure of that object in another system.](https://reader034.fdocuments.us/reader034/viewer/2022051305/5a4d1b777f8b9ab0599b7714/html5/thumbnails/8.jpg)
How to Use a Ruler• Place the end of the ruler to the end of your
object to be measured. * Be sure to check where your ruler begins.
• Most rulers have 16 marks.• Use your knowledge of equivalent fractions to
complete the chart.

Using a RulerUse a Ruler to measure the following items and
record your data:• A brand new crayon
• Your pencil• A large paper clip
• The width of a piece of notebook paper• The length of your desk• The width of your shoe
• The length of your index finger
Be sure to give a precision measurement

Estimation/Guessamation• When determining length we often use
estimation.• Use your reasoning skills to determine the
length of the following and then measure the actual measurement:
an markerpaper clip
pencilan object of your choice

Linking up to ScienceEchoes can be used to measure distance. Weather forecasters send a sound
waves toward weather system such as tornadoes or hurricanes. They time how long it takes the waves to reach a system, “bounce off” it and return. This method of measuring distances is called sonar.
Solve.
1.A ship was in a heavy fog. The navigator knew there was an iceberg nearby, and sounded a horn. Four seconds later he heard an echo returning from the iceberg. Sound travels about 1,100 feet per second in the air. About how far was the iceberg from the ship?2.Sound travels about 1 mile per second in water. Suppose a ship’s sonar emits a loud sound under the water. Four miles away there is a submarine. How long will it be before the echo reaches the ship?3.Write a problem using echoes to measure distances. Have a classmate solve your problem.

Metric Length10 millimeters (mm) = 1 centimeter (cm)
100 centimeters = 1 meter (m)1,000 meters = 1 kilometer (km)
Use the bicycle to help your remember the Metric length terms:
• A millimeter (mm) is about the thickness of a spoke on a bicycle wheel.
•A centimeter (cm) is about the thickness of a bicycle pedal.
•A meter (m) is about the height of a bicycle.
•A kilometer is how far you can ride a bicycle in a few minutes.

Estimate, Measure and Record
Estimate and measure each using the Metric units. Record your data in a table.
• The length of your desk• The distance from your desk to the door
• Your height• Thickness of your Math book
• Width of your pencil

Making ConnectionsYou can find the length or height of something that you can not reach by making connections.
Find the height of this building.
•The height of one floor is 14.5 meters.•Determine how many floors this building has.•Multiply the numbers of floors by the height of one floor to determine the height of this building.
What if:The height of one floor of this building were 12.25 meters?Explain how to find the height of the building.

Find the Measurement using Metric Units:
1. The length of a road 12 blocks long if 1 block is 0.125 km long
2. The height of a building 12 stories high if 1 story is 13 m long
3. The length of a floor 92 tiles long if 1 tile is 30 cm long.

Do you Agree? Explain.1. Anne says 0.2 cm is the same as 2 mm.
2. Joel says that 40 cm is the same as 0.4 m.
3. Jason has 14 yd of string. He used 5 yd 8 in for his project. He claims that he has 8 yd 2 in left.
4. Grace has 13 ft of fabric. She only needs 4 ¼ yds. She thinks she has enough fabric.
