If you met a snake, would you rather meet a long snake or a short snake? Would you stick around to measure it? Using video and online resources, you will learn how to measure things short and tall!
Imagine your favorite cookies are on the top shelf of your cupboard and you can't reach them! Think about your family.
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.
Short is another word we use to compare lengths.
Great job! You just compared your toys by length!
Length is the distance from one end to the other end.
For example, the red line is the length of this puzzle piece:
Different puzzle pieces have different lengths.
For example, these two puzzle pieces have different lengths:
I bet you used your eyes to compare the two puzzle pieces!
You can also measure the lengths! Sometimes you will use rulers, tape measures, or meter sticks to measure lengths.
Let's use ants! Ants are smaller than puzzle pieces, so that will be a good unit of measurement to find these lengths:
When finding the measurement of an object, we make sure to line the unit up end-to-end without overlapping.
For this example, the ants are lined up end-to-end and the ants are not overlapping.
We can then find the lengths. The blue puzzle piece is 3 ½ ants long and the green puzzle piece is 2 ants long. We know that 3 ½ is a larger number than 2.
This proves the blue puzzle piece is longer than the green puzzle piece because it has the greater measurement!
