“I can state the appropriate measure and degree of accuracy.”

What will you be doing?

You will be learning about units of measurement for Length, Weight, Capacity/Volume, and Time.

You will need to know what kind of units you can measure with.

You will also need to choose the best unit of measure and explain why it is the best.

Units of Measure

Units of measure are the names of measurement we use when we measure.

Ex: 1 inch, 1 foot, 1 mile = 1 unit of measure for length.

There are lots of different units to choose from and some tools use more than 1.

How to Measure

When we measure, we need to 1st choose the units that go with what we are measuring.

Then we need to choose the most appropriate type of unit for that measurement.

How to Measure

Choose the right units for length, weight, capacity/volume, or time. Ex: You don’t measure weight with hours!

Choose the unit that makes sense. Ex: You don’t measure your height in miles! Ex: It would take you weeks to measure a

swimming pool with a teaspoon!

Measurements shouldn’t be in decimals nor should they be gigantic numbers!

Types of Measurement

Types of units for a measure

Metric & U.S. Custom units

Unit equivalents (something that is almost the same as the unit in real life or could be used to measure with).

How to write this all down-

The left side of the page will be about Metric, the right side will be about U.S. Custom.

Save room between each word so that you can write an equivalent object of measure.

That’s all there is to write…

Now you need to: Start measuring Choose units to measure with Decide which units work best Explain why some units are better than

others for certain measurement jobs

Use this as a reference if you forgot something!

1 Last Note!

Think about what you need to measure-

Is it very tiny, small, large, or huge?

This will make a difference about what unit to choose. Your measurements shouldn’t be in decimals nor should they be gigantic numbers!
