will use their data to equally redistribute the times to determine an average time, understanding and computing the mean of a set of data is a sixth grade standard. COMMON MISCONCEPTIONS Students might confuse a line graph with a line plot. Review the purpose of a line plot (a graphic representation that shows the frequency of data using or dots along a number line) versus that x’s of a line graph (a graphic representation that shows how data changed over time). ESSENTIAL QUESTIONS How is data collected and displayed on a line plot? What strategies help when solving problems with line plots? MATERIALS a recording sheet “Sing Song” Clock with second hand or other timer device GROUPING Small group task TASK DESCRIPTION, DEVELOPMENT AND DISCUSSION In this lesson students will record the number of minutes that it takes to sing a song or read a poem. They will record their times as fractions and mixed numbers on a line plot and redistribute those times equally to determine the average. Students will work in small groups to sing a song or read a poem and measure the time it takes to sing or read to the nearest five seconds or twelfth of a minute. They will record their fractions or mixed numbers and apply their knowledge of equivalent fractions to express each fraction or mixed number in simplest form. Students will use the data from each person in the group to create a line plot. As a final students will analyze that data to determine an average time by equally redistributing each data point. TASK As a class, decide on a song that students will sing, like Happy Birthday, or a poem to read. Estimate the amount of time that it will take to sing or read it. Discuss how to time
