Measuring Length and Line Plots

1. Use a ruler to measure. The pencil below starts at $0$ inches and ends at the mark shown.

$|{\underbrace{\rule{5cm}{0.5pt}}_{\text{pencil}}}|$ $0 \hspace{4.5cm} ?$

The ruler shows marks at $1, 2, 3, 4, 5$ inches. The pencil reaches the $5$-inch mark.

The pencil is $\underline{\quad}$ inches long.

If you had a crayon that is $3$ inches long, which is longer — the pencil or the crayon?

The $\underline{\qquad\qquad}$ is longer.

2. Estimate the length of each object. Then choose the best estimate.

A school desk — which is the best estimate?

a) $2$ inches $\quad$ b) $2$ feet $\quad$ c) $2$ miles

A paperclip — which is the best estimate?

a) $1$ inch $\quad$ b) $1$ foot $\quad$ c) $1$ yard

3. Five students measured the length of their shoes. Here are the lengths in inches:

$5, \; 6, \; 5, \; 7, \; 6$

Create a line plot by placing an X above each number for each measurement:

$\begin{array}{ccccc} & & & & \\ \hline 4 & 5 & 6 & 7 & 8 \end{array}$

How many students have shoes that are $5$ inches long? $\underline{\quad}$

What is the most common shoe length? $\underline{\quad}$

4. A class measured the lengths of their pencils (in inches): $4, 5, 4, 6, 4, 5, 7, 5$.

Here is a line plot:

5. Sam says his book is about $9$ inches long. He measures it and gets $8$ inches.

Is his estimate reasonable? Circle: Yes / No

Explain why: $\underline{\qquad\qquad\qquad\qquad\qquad\qquad}$

A ribbon is $12$ inches long. A string is $1$ foot long.

Are they the same length? Circle: Yes / No

Hint: $1$ foot $= 12$ inches.
