Practical Applications

Measuring and Comparing Lengths

Measuring in Inches and Centimeters

You'll use rulers and measuring tapes to find out how long things are. You can measure in inches (in) or centimeters (cm).

Comparing Lengths

Use subtraction to find out how much longer or shorter one thing is than another.

Why Measuring Is Helpful

Measuring helps you build things, know if something fits, or compare heights with friends!

Examples

  • Measuring your desk with a ruler to see if it's longer than your book.

  • Subtracting to find the difference between two pencils' lengths.
