How Long is It?

We use rulers to find the length of objects. Today, we'll use Inches and Centimeters.


The Golden Rule: Start at Zero

Always line up the edge of your object with the 0 mark on your ruler.

📏 Inches (in): Bigger units. About the length of a paperclip.

📏 Centimeters (cm): Smaller units. About the width of your pinky finger.

Hint: There are about 2 and a half centimeters in 1 inch!
