Nonstandard Units of Length

In this video, we will learn how to use real-world objects to help us measure and compare lengths.

How could we measure the length of this spade? We could use paper clips to find out how long the spade is. There’s one, two, three, four, five. The spade is about five paper clips long. How long is this baseball bat? We could use cubes to measure its length. How many cubes long is the bat? One, two, three, four, five, six, seven, eight, nine. The baseball bat measures nine cubes long. Let’s practice using everyday objects to help us measure length.

Using paper clips as units of measurement, how long are the scissors?

In this question, we have to measure the length of the pair of scissors, and we’re told to use paper clips as our unit of measurement. So, we need to measure the scissors using paper clips. To find the length of the scissors, we need to count the number of paper clips. One, two, three, four. The scissors are four paper clips long.

Olivia is measuring items with square units. Count to find the missing number. The pencil is what units long.

In this question, Olivia is using squares or square units to measure her pencil. To help us find out the length of the pencil, we have to count the number of square units. Let’s count. One, two, three, four, five, six, seven. We counted the number of square units.

The pencil is seven square units long.

Is the pen longer or shorter than the pencil?

In this question, we’re being asked to compare the length of a pen and a pencil. And we’re given a paper clip to use as our unit of measurement. This means we need to measure the pen and the pencil using paper clips. First, let’s measure the length of the pencil. How many paper clips long is it? The pencil is about five paper clips long. And the pen is almost seven paper clips, or about seven paper clips long. Seven is greater than five. So, the pen is longer than the pencil.

Madison is measuring her toys with unit squares. Pick the toy that is eight units long.

Madison is measuring her doll and her train, and she’s using squares to help her measure. Which of her toys is eight units long? Is it her doll or her train? How many squares long is Madison’s doll? It’s four square units long. How long is her train? Eight square units long. This is the toy we’re looking for. This is the toy that is eight units long.

What have we learned in this video? We’ve learned how to use nonstandard units of measurement to measure length. And we’ve learned that we can use real-world objects such as cubes or paper clips as units of measurement.
