Functions Lesson Plan for 8th Grade Example Students

Topic: functions

Objectives & Outcomes

• By the end of this lesson, students will be able to identify functions using function notation, determine the domain and range of functions, and use functions to solve real-world problems.

Materials

• Whiteboard and markers
• Handouts with examples of functions in function notation
• Calculators

Warm-up

• Ask students to think of a function they have seen before.
• Write down their answers on the board.
• Ask students to share their answers with a partner.
• Encourage them to explain how they determined the function was a function.
• Once all answers have been shared, discuss as a class.

Direct Instruction

• Introduce the term "function."
• Define a function as a relationship between two variables in which each value of one variable is associated with exactly one value of the other variable.
• Provide examples of functions using function notation.
• Discuss how to identify functions using function notation.
• Use the handouts to show examples of functions and their corresponding function notations.
• Have students work through a few practice problems using function notation.

Guided Practice

• Distribute the worksheets with function notation problems.
• Walk students through the problems, providing assistance as needed.
• Assess comprehension by having students work through a few more practice problems on their own.
• Review any incorrect answers and explain how to arrive at the correct solution.

Independent Practice

• Have students work on more problems using function notation.
• Encourage them to use their calculators if necessary.
• Allow them to work at their own pace, checking in occasionally to assist with any difficulties.

Closure

• Review the key points of the lesson, including the different ways to represent functions, how to use function notation, and how to interpret the variables in a function.
• Ask students to share one thing they learned about functions today.

Assessment

• Collect and review the worksheets the students completed during the lesson.
• Use the presentations the students gave during independent practice as a form of assessment.
• Use the class discussion during guided practice as a form of assessment.
• Use the closure as a form of assessment.
