**Grade 4 Measurement** - 4.MD.A.2

What Are Metric Units of Measure? Just like in the English Language, we have synonyms for one word; in math, we have a system of measurements of units. This system is known as Metric Units of measure. The Metric System is an internationally recognized system of measurement. We use this system very frequently in our daily lives such as for the measurement of flour, oil, water, how heavy an object is, and so on. Today, Metric System has seven most common base units: for length, meter is used. For mass, kilogram, time is denoted by seconds, electrical current is measured in amperes, the base unit for temperature is kelvin, luminous intensity is denoted by candela, and the unit for measuring quantity is mole. The metric system units is a convenient way to understand the different values and their respective units. They help us understand the concept better! These worksheets and lessons help students learn how to perform a wide array of math operations on values that include units of measure.

#### Homework Sheets

Instead of using the standard word or story form, I choose to set them up as operational problems.

- Homework 1 - Start with the fact that 1 gallon= 8 pt.
- Homework 2 - We subtract measures at two units.
- Homework 3 - This covers many measures including length, liquid, and days.

#### Practice Worksheets

I realized that I left sums out of this. Probably because they are a bit too simple for this level.

- Practice 1 - Just about every operation you can think up.
- Practice 2 - Find the final value of the following problem.
- Practice 3 - All pretty straight levels of division.
