Facts and Definitions

Lesson 1: Reviewing Customary and Metric Units

• 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
• Units of length indicate how long, high, wide, or far away something is.
• Units of weight/mass show how heavy or light something is.
• Units of capacity tell how much liquid a container can hold; capacity is also referred to as liquid volume.

Lesson 2: Converting Units of Measurement

• When you are converting from a large unit of measure to a small unit, you need to multiply (for example, 3 ft=? in.; 3 × 12 = 36 in.)
• When you are converting from a small unit of measure to a large unit, you need to divide (for example, 36 in.=? ft; 36 ÷ 12 = 3 ft)

Lesson 3: Measurement Problem Solving

Lesson 4: Working With Time

• When you are converting from a large unit of time to a small unit, you need to multiply (for example, 4 hours = ? minutes; 4 × 60 = 240 minutes), and when you are converting from a small unit of time to a large unit, you need to divide (for example, 540 seconds = ? minutes; 540 ÷ 60 = 90 minutes)

Lesson 5: Working With Line Plots

• 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.
