I begin this lesson by watching the video “Math Monsters: Data Collection”. I use this video because it shows the various ways to gather data and put the data into charts and graphs.
One of the difficult portions of MD.C.4 is having students ask and answer questions about graphs. In this lesson students will come up with their own data question and create a chart and graph using the data collected.
As children use different methods to represent data, they must be careful to label their graphs and charts accurately. In this lesson, children will learn how to convert information from a tally chart to a bar graph. They will also discover the importance of labeling and attending to precision (MP.6).
After watching the video, I direct the class to a chart that we have created titled “I Love Spring”. We review the data collected in the chart by comparing each category. We discuss which one is greater than, less than and add them together. After discussing the chart, I ask the students:
I review the elements of our graph: the title of the graph and the labels. I then display the Represent Data.ppt slides and begin discussing the graphs. Looking at the first slide, I guide the discussion:
Brad sees many animals at the park. How can you find how many animals Brad sees?
Work through the Problem Solving graphic organizer together. Ask the following questions to lead children through the solution.
I then display the second slide, and hand out the student worksheets. I read question 1 with children. I then use these questions to guide them through the problem.
I work through the second problem on the worksheet in a similar manner. I then review the question number 3 on the worksheet and direct students to ask 10 classmates about their eye color. I then have children complete the remainder of the Represent Data_worksheet.docx.
To close out the lesson, I have students get their math journals and write the names of 3 types of animals. They then count the letters in each name and make a bar graph showing the letters for each animal.
