When you measure something with a ruler, you should start at the end where the number is "0."

• True

• False

Answer explanation

When you measure with a ruler, starting at the end where the "0" is helps you know exactly how long the object is. The "0" mark is the starting point for your measurement. If you start at any other number, your measurement will be incorrect because you won’t be using the whole length of the ruler to find out how long the object really is. It’s like starting a race at the finish line instead of the starting line!

Draw a simple picture of an object in your classroom (like a marker, desk, or book), and then label it with an estimated length in inches.

• Example: Draw a marker and write “This marker is approximately 4 inches long.”

Answer explanation

When measuring, we guess how long the object is based on how it compares to the ruler.

Name one object in your classroom that you think is longer than your ruler. How do you know?

Answer explanation

You might think the desk is longer because when you look at it, it seems bigger than your ruler. You can also see that the desk goes past the end of the ruler when you try to measure it.

Which of the following is the best way to measure a book?

• Measure from the middle of the book

• Measure from one end of the book to the other end

• Guess how long it is

• Measure the height of the book only

Answer explanation

To find out how long a book is, you should measure all the way from one side to the other. This gives you the total length.

Why do you think it is important to measure things accurately? Give one example to support your answer.

Answer explanation

It’s important to measure correctly so we know exactly how long or wide something is. For example, if you want to put a box on a shelf, you have to measure the box and the shelf to make sure the box fits! If you don’t measure right, the box might be too big!
