Learning how to create line plots is a second grade, Common Core math skill: 2.MD.9. Below we show two videos that demonstrate this standard. Then, we provide a breakdown of the specific steps in the videos to help you teach your class.
Your students will have learned how to measure objects through non-standard units, like using paperclips to measure a pencil (1.MD.1). They should also be able to compare objects using terms like longer, shorter, longest, and shortest (1.MD.2).
In the future, understanding how to measure objects with a ruler will help your students expand on and apply the concept elsewhere. Students will be able to make a line plot, measure objects, and place those measurements on the plot (2.MD.9). Your students will also be able to use rulers marked with halves and fourths of an inch (3.MD.3) and apply “linear measurement to measure perimeter and area” (3.MD.5- 8).
Common Core Standard: 2.MD.9 - Generate measurement data by measuring lengths of several objects, or the same object, to the nearest whole unit and make a line plot to show the data
Students who understand this principle can:
2 Videos to Help You Teach Common Core Standard: 2.MD.9
Below we provide and breakdown two videos to help you teach your students this standard.
Video 1: Creating a Line Plot with Number One
The Number One leads viewers through the process of building a line plot. First, he gathers the data that will be used on the line plot. To gather the data, One measures the lengths of various objects, writes those numbers on a piece of paper, and uses that information to construct the line plot.
His friend Speedy the snail brings objects for One to measure.
These measurements are then included in a list of measurements that One already measured. Next, One goes through the steps of building a line plot.
The data from the measurements is filled into the line plot. Below is a picture of the completed line plot from the video.
The video ends by asking viewers to identify how many objects were 6 inches long. There were 4 objects that were 6 inches long, and the 4 Xs represent that.
Video 2: Understand and Create a Line Plot
The video starts by explaining what a line plot is and how it is used: “A line plot is a graph that shows the frequency of data along a line.” Then, Boddle explains frequency and data.
Boddle then looks at an example of a line plot to see how it works. The graph shows the number of students who have lost their pencils within the week.
Next, Boddle creates a line plot with the students. A teacher has collected the scores for a math assignment and listed them in a table. Below is a picture of the table from the video.
Boddle then goes through the steps on building a line plot.
Below is a picture of the finish line plot from the video.
Based on the line plot, viewers can see that most of the students scored a 28 out of 30. Also, the lowest score was 26, and the highest was 30.
