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.
