Facts and Definitions

Lesson 1: Customary and Metric Units

• Standard units of measurement: agreed upon units of measurement that are typically used (for example, inch, foot, centimeter, meter)
• Customary system: the main system of measurement used in the United States, also called the US Customary System
• Metric system: the system of measurement used in most countries other than the United States, based on the number 10
• Length: how long, wide, or high something is (length can also measure distances)
• Weight: how heavy or light something is
• Liquid volume: how much liquid is in a container
• Capacity: how much liquid a container will hold

Lesson 2: Converting Units of Length

• Equivalent customary lengths: 12 inches = 1 foot; 3 feet = 1 yard; 5280 feet = 1 mile; 1760 yards = 1 mile
• Equivalent metric lengths: 10 millimeters = 1 centimeter; 100 centimeters = 1 meter; 1000 millimeters = 1 meter
• Metric length abbreviations: millimeter = mm; centimeter = cm; meter = m
• Customary length abbreviations: inch = in.; foot = ft; yard = yd; mile = mi

Lesson 3: Converting Units of Weight

• Equivalent customary weights: 16 ounces = 1 pound; 2000 pounds = 1 ton
• Customary weight abbreviations: ounce = oz, pound = lb; ton = T
• Equivalent metric weights: 1000 milligrams = 1 gram; 1000 grams = 1 kilogram
• Metric weight abbreviations: milligram = mg; gram = g; kilogram = kg

Lesson 4: Converting Units of Capacity

• Equivalent customary capacity: 1 tablespoon = 3 teaspoons; 1 fluid ounce = 2 tablespoons; 1 cup = 8 fluid ounces; 1 pint = 2 cups; 1 quart = 2 pints; 1 gallon = 4 quarts
• Customary capacity abbreviations: teaspoon = tsp; tablespoon = tbsp; fluid ounce = fl oz; cup = c; pint = pt; quart = qt; gallon = gal
• Equivalent metric capacity: 1000 milliliters = 1 liter
• Metric capacity abbreviations: milliliter = ml; liter = l or L

Lesson 5: Practice and Problem Solving

• A line plot is a graph that shows information along a number line. Each X above a number equals one person or thing being measured.

Lesson 6: Working With Time

• There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week
• One year is equal to 12 months, 52 weeks, or 365 days
• A leap year is 366 days long and occurs every 4 years
• A decade is 10 years, a century is 100 years, and a millennium is 1000 years

Lesson 7: Reviewing Perimeter and Area

• Area: the measure of space within a plane or two-dimensional shape, the number of square units within a plane or two-dimensional shape
• Perimeter: the distance around a plane or two-dimensional shape
• The perimeter of a shape is the sum of all of its sides
• The area of a rectangle is its length times its width
