Lesson Plan - Get It!

Audio:

Imagine your favorite cookies are on the top shelf of your cupboard and you can't reach them! Think about your family. Who is the tallest person who can get those cookies for you?

"Tall" is a word we use to compare lengths, or how long something is.

Since you want the person who is the longest to reach up and get those cookies, you want the tallest person. Why wouldn't you want the shortest person to try and get them? "Short" is another word we use to compare lengths.

Go into your room and see if you can find your tallest stuffed animal, doll, or action figure.
Now, hunt for the shortest one.

How did you know which one was the tallest?
How did you know which one was the shortest?

Great job! You just compared your toys by length!

When we want to measure an exact length we need to use a ruler or tape measure, but if we are just comparing length we don't need them; we can use our eyes to tell the difference.

Watch this Turtle Diary video on Length Measurement to see how other objects are compared.

Is there a word you didn’t know in the video? What was it? What do you think it means?
If you knew all of them, pick one word and share what it means to you with your teacher.

Now, continue on to the Got It? section to go outside and measure some things!
