Measurement Detective Scavenger Hunt!

Get ready, Detective Karina, for a mission to find and measure objects!

Warm-up (5 minutes)

Let's quickly review our measuring tools. Look at your ruler and measuring tape. Can you find the side with inches? An inch is part of the imperial system. Now find the side with centimeters. A centimeter is part of the metric system. We use both systems!

• 1 foot (ft) = 12 inches (in)
• 1 meter (m) = 100 centimeters (cm)

Let's practice measuring one thing together, like the width of this piece of paper, in both inches and centimeters.

Activity: The Scavenger Hunt (30-40 minutes)

Here is your list of clues, Detective Karina! Find the items, measure them carefully, and write down your findings on your Scavenger Hunt Sheet.

Your Mission List:

1. Find a book. Measure its length in inches AND centimeters. Record both.
2. Find a spoon. Measure its length in centimeters.
3. Find something in the kitchen that is SHORTER than 6 inches. What is it and how long is it in inches?
4. Go outside (or look out a window)! Find a leaf. Measure its width in centimeters.
5. Find something inside that is taller than you (use feet or meters!). What is it? (Estimate if too tall to measure exactly).
6. Find a crayon. Measure its length in inches AND centimeters.
7. Find something round. Measure the distance across it (diameter) in inches.
8. Locate an object that is approximately 1 foot long. What did you find?
9. Find something that is about 30 centimeters long. What is it?
10. Measure the width of a door in inches.

(Optional Extension: Can you convert one of your inch measurements to centimeters, or centimeters to inches? Remember: 1 inch is about 2.5 cm)
