Eureka Math Grade 3, Module 6: Collecting and Displaying Data
In this unit, your child collects data and shows it on picture graphs, bar graphs, and line plots. They choose a scale, such as each square standing for 5, and answer how many more and how many fewer. They also measure lengths to the nearest quarter inch and plot them, using the fraction work from the last unit. Geometry and measurement problems come next.

What is my child learning in Module 6?
- Drawing bar graphs with a scale that counts by 2s, 5s, or 10s, and solving how-many-more questions from them. Learn more: Reading picture graphs and bar graphs
- Measuring lengths with a ruler marked in halves and fourths of an inch, then showing the data on a line plot. Learn more: Measuring to the nearest quarter inch
Sample questions to try together
These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
Look at the bar graph. How many more students chose Green as their favorite color than Blue?
- 10
- 4
- 6
How you can help
- Count the socks in the laundry by color and draw a bar graph where each square stands for 2 socks, so 10 white socks fill 5 squares.
- Measure 5 crayons to the nearest quarter inch, write each length, and draw a line plot marked in quarter inches to show them.
- Ask your child what each line on the side counts by when you spot a bar graph on a cereal box or in a store flyer.
Where kids can get stuck
- Reading the halfway mark between 4 and 5 inches as 4 1/4, mixing up half-inch and quarter-inch marks.
- Ignoring the key on a picture graph, so 4 pictures worth 5 votes each read as 4 votes.
- Lining up the object with the 1 on the ruler, so every length comes out 1 inch too long.
Practice makes perfect
Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
Words your child will hear
- data
