COMMON CORE STANDARDS
• 6.MD.1. Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.

Objectives
• Students will be able to: Describe a brief history of the metric systemIdentify units in the metric systemConvert units within the metric systemCompare and Contrast the metric system and
the customary system of measurement

MeasurementMeasurement can answer many
kinds of questions. For example:How far?How much?How fast?What temperature?
What time?How high?How deep?
And many more…

Metric Video
• Everyday Measurements
• Brief History of the Metric System

What was early measurement based upon? • Parts of peoples bodies.
• Such as finger, hand, arm, foot, etc.
How is this a problem?People are different sizes, so the measurements could be different.

How was the problem fixed?They chose the parts of one persons body for measurement. Whoever was the current ruler of the kingdom.
How was this a problem?The rulers changed over time and the measurements with them.

How was this problem fixed?They stopped changing it
whenever a new king or queen came into power.

The Metric System• Why the metric system?It is a scientific system that is
standard all over the world. Except one place…

What is Volume?• The amount of space a substance
occupies as measured in liters.
What is used to measure liquid volume? • A graduated cylinder.
Volume of objects can also be measured by multiplying the length X width X height.

• Measuring volume
• Measuring Mass

Water Displacement• Water displacement is a way to
measure the volume of an irregular object.
• This works because an object will displace an amount of water equal to its volume when it is submerged.

Weight vs. Mass• Weight -is the effect of gravity on
an object.• Mass -is the measure of the
amount of matter in an object.• Mass is measured in grams. Often
measured with a balance.

Length• Length- the distance between
two points• Length in the Metric System is
measured in meters.
