No, a line graph does not tell us how many lines are in a drawing.

Incorrect. A line graph must include how data changes over time.

Try again. A line graph must also include how that number has changed over time.

Yes! A line graph uses points to show how something changes over time.

No, a line plot does not tell us how many lines are in a drawing.

Incorrect. A line plot might tell us how many people are in our class, but it would have other information too.

Try again. A line plot will tell us about the number of items but not about how often we can plot a line.

Yes! A line plot uses Xs to show how many times something happens.

Yes. Data is information that is collected by asking questions or observing how often something occur.

Try again. You can have more information than can fit on a graph.

Try again. The Xs in a line plot record the frequency of each item; data tells you what that X represents.

Yes. The Xs above the label on the line plot show the frequency.

Try again. Counting all the Xs would add up all the information on the line plot.

Try again. Counting the number of items being compared tells us what is being compared, not how frequently they occur.

Yes. Three people chose blue or yellow; 2 chose blue, and 1 chose yellow for a total of 3.

Try again. Count the number of Xs above both labels.

Try again. Count the number of Xs above both labels.

Try again. Count the number of Xs above the blue and yellow labels.

Yes. The labels show which types of items you are counting in the line graph.

Try again. You must record all the types of items on the line graph.

Try again. The Xs record the frequency of each item; the label tells the type of item.

Incorrect. Line plots do not record change over time.

Correct. Line plots represent how often something occurs.

Incorrect. Line graphs display how often one item is sold over time.

Incorrect. Line plots represent how often something is chosen.

Incorrect. Line graphs need to record change over time; this is just one item.

Correct. Line graphs represent how often something occurs over time.

Incorrect. Line graphs display how often one item is sold over time; this is for only one time period.

Incorrect. Line graphs represent the change over time, not location.

Correct. This array has 2 white, 2 black, 3 orange, and 3 yellow hard hats.

Incorrect. This line plot does not show enough hats.

Incorrect. This line plot shows only 5 data points instead of 10.

Incorrect. This line plot shows too many orange and yellow hard hats.

Great job! Line graphs show the change in something over time.

Try again. While you may use tallies to record your data, a line graph would be the best way to display this data.

Try again. Bar charts do not record change over time.

Try again. A line plot records data on a number line; however, this data shows a change over time.
