Measurement Maniac



Today, we are going to put your estimation skills to the test! This isn't the first time you estimated the amount of something. In the beginning of the year, we took a poll on the amount you thought was in this jar filled with jelly beans!

Ahoy Matey! You have just found out that there are some very special valuables in this classroom and you must go on a measurement hunt in order to find the correct items! Your pirate skills will come in handy in your search for booty, but first, you must know how to measure! You will be given a piece of yarn to help you measure in order to find something shorter, longer, and equal in size. Yo ho ho, will you be able to find the hidden treasure or will you be forced to walk the plank?


How can you measure length with and without a ruler?

You have already learned how to measure with a starting line. Remember that you cannot compare the length of 2 or more objects without placing them on starting line. Just as two runners in a race must start at a starting line to have a fair chance, so too must you use a starting line to give each item a fair chance. Now that you know how to measure you will use your skills to find 3 objects in the classroom: one must be SHORTER than your piece of yarn, one must be LONGER than your piece of yarn, and one must be EQUAL size in length to your piece of yarn. You will measure and compare the 3 items using your piece of yarn. At the end you will draw your 3 items on a worksheet and answer the following questions:

What strategy did you use on your hunt?

Did you measure everything in sight?


For this activity, you will need the following materials:
-A box of paperclips
-A shoe (your own)
-Book (math book)
-Stapler (on my desk)

1. Play this game at, Start on the easy level and work your way up!
2. Sign into brainpopjr.
3. Go to the math page and select "measurement."

4. Search around the room for something LONGER than your string.
5. Search around the room for something EQUAL in length to your string.
6. Gather your 3 items and draw each item in the appropriate box on the following worksheet (attach).
7. Answer the following questions on your worksheet:

What strategy did you use on your hunt?

Did you measure everything in sight? Explain.
