Procedure: 

Note:
This lesson can be used after the students have had an introductory lesson on creating and interpreting bar graphs. At the end of the introductory lesson, a class survey should be taken on a student generated topic such as a favorite type of vacation or favorite activity. That information will be used for this lesson. For this lesson, the students will be using an online bar graph maker called “Grapher” to create a bar graph.
Activity 1

Review the parts of a bar graph by playing a game on Kahoot! or by displaying a bar graph with a list of terms and using a Turn and Talk so students can share their thoughts with the class.

Display the survey results from the concluding activity of the previous lesson. In the previous lesson, the students learned the parts of a bar graph, determined an appropriate scale based on the data, drew the bars based on the data, and answered questions about the bar graph.

Pass out the survey from the previous lesson and discuss the results as a group.

Ask students to open up Grapher on their computers.

Go over the parts of Grapher with the students, pointing out that although bar graphs can be vertical or horizontal, this particular graph will be a vertical bar graph due to the format of this site.

Have students identify the x axis, the y axis, the scale, the title, and the labels. Discuss where their survey information will be located on the graph that we will be creating using this site.

Model how to highlight the title on the graph so that they can type in a new title for our class bar graph. Then model how to highlight and change the x axis and the labels as well, allowing the students some time to complete this. As a class, discuss whether the scale on Grapher will work for the information on our class bar graph.

Based on the discussion, have the students come up with 2 appropriate scales for our graph. Have half of the class use one scale and half use the other scale. Model how to highlight and change the existing numbers, and ask the students to label their graph using one of the 2 scales.

The final step is using the triangles under the labels on the x axis to show how many students selected the first category on the bar graph and continue until all of the data has been entered. In pairs, the students should compare the 2 scales that were used for this graph. How did the scales change the look of the graphs? Is one scale more accurate than the other? In their math journals, each student should write a 1 step or 2 step word problem that directly relates to the bar graph we created. Ask a few volunteers to share their word problems with the class.
Activity 2

To practice independently, the students will be given a new frequency table and asked to use Grapher to create a bar graph to show the data. Allow students to work independently, Students who need support can work with the teacher in small group.

Students will create a 1 or 2 step word problem based on the information in their bar graph in their math journals. When the students are finished, they can print out their bar graphs and then cut out and glue their word problem on their graph.

In any remaining time, have the students share their graphs and word problems in small groups. Review the learning target for the lesson. Have the students complete an exit slip that assesses how well they think this interactive tool helped them show and interpret data.
