Learning Objectives

Students will be able to make a bar graph to represent data.

Lesson

Introduction (5 minutes)

  • Take a quick poll from students on what their favorite season is.
  • Use tally marks, and record results on the board.
  • Tell students that today they are going to use data to make bar graphs.

Explicit Instruction/Teacher Modeling (10 minutes)

  • Use the data from the board on favorite seasons to make a bar graph.
  • Draw the bars on chart paper to show each number.
  • Write the title Favorite Seasons at the top of the graph, and explain to students that bar graphs should include a title.
  • Explain to students that bar graphs also need a scale, scale label, categories, category label, and data.
  • Continue completing the bar graph by adding the rest of the labels and the data.
  • Discuss each part of the graph with your students.

Guided Practice/Interactive Modeling (15 minutes)

  • Write various colors on the board.
  • Take a poll, asking students to name their favorite colors.
  • Draw tally marks beside each color as students name their favorites.
  • Display a copy of the blank bar graph sheet for students to see.
  • Write in the color words at the bottom.
  • Have students take turns shading one bar on the sheet to represent their favorite colors.
  • Point to the bottom of the graph, and ask what label should be on it (colors).
  • Draw a line under the color words for the label and write Colors.
  • Point to the left side of the graph, and ask your students to label it.
  • Write Number of Students on the left side of the graph.
  • Ask questions about the graph to check for understanding. For example: Which color is most liked? How many people like red?

Independent Working Time (10 minutes)

  • Give students the Jake's Nature Hike worksheet.
  • Read over the directions with the students.
  • Have students complete the graph on their own.

Extend

Differentiation

  • Enrichment: For advanced students, instruct them to create their own questions other students can answer by using the data in the graph. For example: How many more people like green than red? Encourage your students to write comparison questions.
  • Support: Help students who need support write the labels on the graph. Instruct them to shade in the bars, showing them how the numbers on the left correspond with how many people like a certain color. Have them create line plots instead of bar graphs until they see the correlation between the numbers on the axis and the number of items.

Review

Assessment (5 minutes)

  • Circulate and observe students as they complete their graphs.

Review and Closing (5 minutes)

  • Ask students to explain how to make a bar graph.
  • Have a volunteer take a quick poll, and invite other students to quickly sketch a graph on the board.
