Lesson 84 of 186

Concept

If you are going to compare lengths, you have to know which words mean big things, and which words mean small things!

🎯 The Customary Size Guide: 1. Inch (in): The smallest. About the length of a paperclip. 2. Foot (ft): Medium size. It is exactly 12 inches glued together. About the length of a real adult's foot (or a school ruler). 3. Yard (yd): The biggest! It is exactly 3 feet glued together (or 36 inches). About the length of a giant adult step, or a baseball bat.

Inch < Foot < Yard

So, if someone says "My car is 12 feet long, and your car is 12 inches long"... their car is a LOT bigger!
