Section 1
Using Double Number Lines for Rate Problems
Property
Double number lines show equivalent rates by aligning corresponding values on parallel lines.
This visual tool helps you see how two different quantities grow at the same time.
In Grade 6 Reveal Math Course 1, Lesson 1-8, students learn to solve real-world rate problems by finding unit rates and applying bar diagrams, double number lines, and equivalent rates. The lesson covers how to calculate unit prices, unit speeds, and rates per minute, then scale those rates to compare and find differences over larger quantities or time intervals. Students work through multi-step problems involving rates such as miles per hour, price per can, and heartbeats per minute.
Section 1
Using Double Number Lines for Rate Problems
Double number lines show equivalent rates by aligning corresponding values on parallel lines.
This visual tool helps you see how two different quantities grow at the same time.
Section 2
Solving Rate Problems with Equivalent Rates
To solve a rate word problem using abstract math, first identify the two quantities being compared and set up two equal rates. Let a variable (like ) represent the unknown quantity. Ensure that the units align perfectly straight across the numerators and denominators.
