Which Customary Unit is Best? (in, ft, yd)
π€ Big or small? Picking the wrong measuring tool can be a disaster! Would you measure a pencil in yards?
Do this: Read the concept below, then try the quiz or activity.
Concept
Let's review how to pick the smartest unit to measure with.
π― The Customary Size Guide: 1. Inch (in): Very small. Best for a cell phone, a mouse, a book, a pencil. (If it fits on a desk, use inches!). 2. Foot (ft): Medium. Best for a person, a door, a desk, a bicycle. (If you can walk across it in a few steps, use feet!). 3. Yard (yd): Huge. Best for a playground, a football field, the length of an airplane. (If you have to run across it, use yards!).
If you measured an airplane in inches, the number would be way too big! "The plane is 1,800 inches long" is silly. It's much easier to say "50 yards"!
