Lesson Plan:
Line Plots: Representing the Length of Classroom Items
October 29, 2015
October 29, 2015
Learning Objectives
Students will be able to measure the lengths of objects and use a line plot to represent the measurement data.
Lesson
Introduction (10 minutes)
- Review measuring items by asking students to explain how to measure using a ruler.
- Pass out rulers, and have students measure the length of their pencils.
- Record their results as numbers on the board.
- Tell students that today they're going to learn about using line plots to display the data they collect from measuring different items.
- Read aloud Kenley's Line Plot Graph: Another Math Adventure by Kathleen Stone.
Explicit Instruction/Teacher Modeling (10 minutes)
- Explain to students that a line plot uses a number line to show data, and that data is information collected about people or things.
- Explain what the different parts of the line plot are, such as the title and axis label.
- Draw a line plot on chart paper.
- Write the title Length of Pencils at the top of the line plot and Inches at the bottom to label the axis.
- Ask students to look at the results from the pencil measurements and find the measurements for the shortest pencil and the longest pencil.
- Label the number line with the shortest pencil as the first mark and the longest pencil as the last mark.
- Draw an X for the length of each student's pencil in a single column above the number on the number line.
- Discuss the line plot with students. Potential questions include: What is the most common length of a pencil in our class? How many pencils are there in all?
Guided Practice/Interactive Modeling (10 minutes)
- Draw a number line from 1 to 6, and label the axis and numbers.
- Have each student measure another person's thumb using an inch ruler.
- Record students' results on the board.
- Ask students to help come up with a title for the line plot.
- Write the title, such as Thumb Lengths, on top of the line plot.
- Have students come to the board and draw an X for the length of their thumbs in a single column above the number on the number line.
- Discuss the line plot by asking questions. For example: What is the most common length of thumbs? How many thumbs are 3 inches long?
Independent Working Time (15 minutes)
- Instruct your students to complete the Line Plot worksheet.
Extend
Differentiation
- Enrichment: Direct your students to come up with their own line plots and questions for other peers to answer. Give them time to exchange worksheets and answer each other's questions.
- Support: Instruct your students to make their own questions and survey the classroom. Have the other students mark their X themselves on the student's graph, helping the student to see that each X belongs to a person.
Review
Assessment (5 minutes)
- Walk around the room, and observe students as they complete the Line Plot worksheet.
Review and Closing (10 minutes)
- Ask students to describe how they made a line plot today.
- Take an easy poll, such as how many siblings your students have, and invite a volunteer to make a line plot on the board to represent the data.

Comparison is one of the most crucial math skills second graders learn, because it can be applied to so many other disciplines across the elementary school curriculum. In this measurement and data lesson, kids will work on object comparison and graphing. The exercises ask kids to list objects in size order, estimate length, note differences in length, and make bar graphs.
