Sommaire

This 3rd grade bar graphs worksheet covers scaled graphs and line plots (Common Core 3.MD.B.3, 3.MD.B.4), with a free PDF to print.

Key takeaway: This worksheet helps Grade 3 students practice scaled graphs and line plots.

Topic: Scaled Graphs and Line Plots (3rd grade)
Content: 20 worksheet problems, from easy to challenging
Standards: 3.MD.B.3, 3.MD.B.4
Answers: On a separate page, so you can try every worksheet problem first
Format: Free printable PDF, US Letter, black and white

This worksheet helps Grade 3 students practice scaled graphs and line plots. First, children read picture graphs where each star stands for more than one item. Then they read bar graphs with a scale that counts by tens.

The 15 problems also measure to the nearest fourth of an inch, read a line plot, and build a line plot from shell lengths. Next, children use halves in picture graphs, find how many more, and add totals. Finally, they solve stories about lemonade, sports votes, and a street fair. Plan about 30 minutes, with a ruler nearby.

These 20 problems practice reading and comparing scaled picture graphs and bar graphs, measuring lengths to the half inch and fourth inch, and reading line plots (3.MD.B.3 and 3.MD.B.4).

Start with the key or the scale, then read the values. The last six problems ask for more than one step, so write each step.

3rd grade bar graphs worksheet: worksheet problems 1 to 10

1 – Read the picture graph

First, each star stands for 4 books. How many books did the Blue team read?

Graph for Problem 1.

2 – Stars for a total

Next, in a picture graph, each star stands for 5 students. How many stars show 35 students? How many show 25 students?

3 – Read the bar graph

Then, how many students chose bananas?

Graph for Problem 3.

4 – How many more pages

Now, how many more books were returned on Thursday than on Monday?

Graph for Problem 4.

5 – Halfway on the scale

Also, the scale on a bar graph counts by 10: 0, 10, 20, 30. A bar ends halfway between 20 and 30. What number does the bar show?

6 – Measure the crayon

First, write the length of the crayon to the nearest fourth of an inch.

Ruler for Problem 6.

7 – Measure the pencil

Next, the pencil starts at 0. Where does its tip end? Write the length in inches.

Ruler for Problem 7.

Worksheet problem 8 and after

8 – Count the marks

Then, a ribbon is \(2\frac{1}{4}\) inches long. How many fourth-inch marks is that from 0 on a ruler?

9 – Read the line plot

Now, how many leaves are 2 inches long?

Line plot for Problem 9.

10 – Longer than the mark

Also, how many ribbon pieces are longer than \(1\frac{1}{2}\) inches?

Line plot for Problem 10.

Worksheet problems 11 and up

11 – Build a line plot

Pedro measures 8 shells in inches: \(1\frac{1}{4}\), \(1\frac{1}{2}\), \(1\frac{1}{4}\), \(2\), \(1\frac{3}{4}\), \(1\frac{1}{4}\), \(2\), \(1\frac{1}{2}\). He makes a line plot. How many Xs go above \(1\frac{1}{4}\)?

12 – Picture graph with halves

Next, each star stands for 10 cans. How many more cans did Room 3 collect than Room 2? How many cans did all four rooms collect?

Graph for Problem 12.

13 – Cups of lemonade

Then, how many cups were sold on Saturday and Sunday together? How many fewer cups were sold on Monday than on Saturday?

Graph for Problem 13.

14 – Sports votes

Now, each star in a picture graph stands for 4 students. Swimming has 7 stars and hiking has 4 stars. How many more students chose swimming?

15 – Street fair

Also, a bar graph scale counts by 10. The Maple Street bar ends halfway between 30 and 40. The Oak Street bar ends at 60. How many more people are on Oak Street?

Worksheet problem 16 and after

16 – Book fair

First, each star stands for 8 books and a half star stands for 4. Room A has 3 whole stars and a half star. Room B has 5 whole stars. How many books do the two rooms have in all?

17 – Pencil lengths

Next, a line plot shows 3 pencils at 4 inches, 5 pencils at \(4\frac{1}{2}\) inches, and 2 pencils at 5 inches. How many pencils were measured? How many pencils are longer than 4 inches?

18 – Raffle tickets

Then, a bar graph has a scale that counts by 5. Sam sold 35 tickets, Tia sold 20, and Uma sold 30. How many tickets did the three students sell? How many more did Tia and Uma sell together than Sam?

19 – Reading minutes

Now, a bar graph has a scale that counts by 2. Maya’s bar reaches 14 books and Leo’s bar reaches 8 books. How many books did they read together? How many more did Maya read?

20 – Pizza slices

Also, each star stands for 2 slices and a half star stands for 1 slice. On Tuesday the picture graph shows 6 whole stars and 1 half star. On Wednesday it shows 9 whole stars. How many more slices were eaten on Wednesday?

Key facts behind this 3rd grade bar graphs worksheet

Key facts

The key tells what one symbol is worth; a half symbol is worth half.
Next, on a bar graph, read the scale before reading a bar.
A bar halfway between two lines is halfway between their values.
Then, a ruler is marked in inches, halves, and fourths.
On a line plot, each X is one measurement.

Common mistakes with this 3rd grade bar graphs worksheet

When a key says each star is worth 5, students count each star as one. First, read the key. Then skip count by 5 for each star.
Also, when a bar ends between two scale lines, students read the lower line. Find the halfway value between the two lines, then read the bar.
When building a line plot, students forget measurements that repeat. Next, put one X for every measurement, even when two are the same.

Tips before you start the worksheet problems

Write the value of each row beside a picture graph. Then add the values for totals and subtract for differences.
For bar graphs, use the edge of a card to line up the top of a bar with the scale.
Also, teachers can ask students to make a line plot of their own pencil lengths. Then they can ask questions about the data.

3rd grade bar graphs worksheet: frequently asked questions

How do you compare two bars on a scaled graph?

Read both bars using the scale, then subtract the smaller from the larger. For example, if one bar is 45 and another is 30, there are 15 more. Also, write the unit in the answer. As a result, small mistakes are easier to catch.

What does the longest X column on a line plot show?

It shows the measurement that occurred most often. Then, count the Xs above each mark and compare. The mark with the most Xs is the most common length. Also, saying the steps aloud helps you spot a slip.

How can you check a measurement to the nearest fourth inch?

Line up the zero mark with one end of the object. Next, read the closest mark at the other end, which may be a whole, a half, or a fourth. Then ask if the length makes sense for the object.
