Kindergarten Bar Graph And Number Line Lesson Plan (Math)

Topic: math: number sense and operations

Objectives & Outcomes

• Students will be able to compare and order numbers using a bar graph and a number line.

Materials

• Bar graph with three categories and four or more items in each category
• Number line with whole numbers from 1 to 20
• Pencils and paper for each student

Warm-up

• Ask students to sit in a circle.
• Show the bar graph and ask students to look at the graph and describe what they see.
• Encourage them to use words such as "more," "less," "bigger," "smaller," and "same."
• Write their responses on the board.
• Next, ask students to sit on the floor in a line, with one student at the beginning and one at the end.
• Show the number line and ask students to look at the line and describe what they see.
• Encourage them to use words such as "more," "less," "bigger," "smaller," and "same."
• Write their responses on the board.

Direct Instruction

• Explain to students that a bar graph is a way to visually show how data is distributed across categories.
• Explain that the height of the bars represents the value of the data, and the width of the bars represents the number of data points in each category.
• Show students the different colors on the bar graph and explain that these represent different categories of data.
• Explain that a number line is a way to visually show the order of numbers.
• Explain that the numbers on the left represent smaller numbers and the numbers on the right represent larger numbers.

Guided Practice

• Have students work in pairs to create their own bar graphs and number lines for the given data sets.
• Give students the bar graph and number line templates and have them use the provided data sets to create their own bar graphs and number lines.
• Have students share their bar graphs and number lines with the class and discuss how the data is distributed across categories.

Independent Practice

• Have students choose their own data sets and create their own bar graphs and number lines.
• Have students present their bar graphs and number lines to the class and explain how the data is distributed across categories.

Closure

• Review the steps for creating a bar graph and number line, including choosing appropriate data, labeling the bars and ticks, and ordering the numbers on the number line.
• Ask students to share any new insights they gained about the distribution of data across categories.

Assessment

• Observe students as they work on their independent practice project and give feedback on their understanding of the concepts.
• Collect and review the completed bar graphs and number lines to assess students' ability to accurately represent and order data across categories.
