Sample of lesson plan grade six on lowest common multiple including skills and values
Lesson Title: Finding the Lowest Common Multiple
Grade Level: 6
Duration: 60 minutes
Objectives:
1. Students will be able to find the lowest common multiple (LCM) of two or more numbers.
2. Students will practice finding the LCM through a variety of methods including prime factorization and the list method.
3. Students will understand the importance of the LCM in solving real-world problems involving fractions and ratios.
4. Students will collaborate and communicate effectively with their peers to solve problems involving the LCM.
Materials Needed:
- Whiteboard and markers
- Pencils and paper
- Worksheets with problems involving LCM
- Calculator (optional)
Warm-Up (10 minutes):
- Begin the lesson by reviewing the concept of multiples with the students. Ask students to give examples of multiples of a given number.
- Discuss how finding the least common multiple can help simplify working with fractions and ratios.
Instruction (20 minutes):
- Introduce the concept of the lowest common multiple (LCM) to the students. Explain that the LCM is the smallest multiple that two or more numbers have in common.
- Demonstrate how to find the LCM using the prime factorization method. Give an example and walk students through the steps.
- Show an alternative method of finding the LCM using the list method. Provide another example for students to practice on their own.
Guided Practice (15 minutes):
- Break the students into small groups and give them a worksheet with problems involving LCM. Encourage them to work together to find the LCM of each set of numbers using the methods learned in class.
- Circulate around the room to provide guidance and support as needed.
Independent Practice (10 minutes):
- Have students work individually on a few additional problems involving LCM. Encourage them to use both the prime factorization and list methods to find the LCM.
Closure (5 minutes):
- Review the concept of the LCM with the students and ask them to share any new insights or strategies they have learned.
- Discuss the importance of finding the LCM in real-world situations and how it can help simplify problems involving fractions and ratios.
Assessment:
- Evaluate students' understanding of finding the LCM through their completion of the worksheet and their ability to explain their reasoning.
- Observe students' collaboration and communication skills during the group work activity.
