Composite Numbers Lesson Plan for 7th Grade Example Students

Topic: Composite Numbers

Objectives & Outcomes

Understand the concept of composite numbers and how to differentiate them.

Materials

Whiteboard or chalkboard

Markers or chalk

Composite numbers worksheet (provided below)

Warm-Up

Ask students if they have heard of composite numbers before. What do they know about them? Write their responses on the whiteboard.

Ask students if they can give an example of a composite number. Write their responses on the whiteboard.

Direct Instruction

Explain that a composite number is a number that is not prime. Composite numbers can be divided evenly by at least one other number besides themselves and 1.

Introduce the concept of differentiating a function. Explain that differentiating a function means finding the derivative of the function, which is the function's rate of change.

Explain that the derivative of a composite number is the sum of the derivative of each of its factors.

Use the whiteboard to illustrate and explain the process of differentiating a composite number. Use the example of differentiating 25. First, find the derivative of 5, which is -20. Then, find the derivative of 2, which is -10. Finally, add -20 and -10 to get -30, which is the derivative of 25.

Guided Practice

Give each student a set of function cards and have them work in pairs. Have them choose a function card and differentiate it using the process explained above. They should then check their work by comparing it to the derivative on the back of the card.

During this activity, circulate and provide guidance as needed. Students may need help understanding the process of differentiating a composite number or in interpreting the derivative on the back of the function card.

Independent Practice

Divide the class into small groups and have each group choose a different composite number to work with. Have each group find the derivative of their chosen number and create a poster to illustrate their process and the derivative they found.

Encourage students to be creative and to use a variety of resources, such as pictures, to help them understand and communicate their process.

Closure

As a class, review the examples and the process for finding the derivative of a composite number.

Ask students to share their posters with the class and explain their thinking.

Assessment

Observe students during independent practice and provide feedback on their derivatives and explanations.

Collect and assess the posters that students created during independent practice.
