Title: Division of Hours and Minutes by a Whole Number

Grade Level: Primary 4

Objective: - Understand the concept of division and its application in dividing hours and minutes by a whole number. - Develop skills in dividing hours and minutes by a whole number. - Apply division skills to solve real-life problems involving time.

Materials: - Clock or watch - Whiteboard or blackboard - Markers or chalk - Worksheets with division problems related to time - Timer or stopwatch (optional)

Procedure:

1. Introduction (5 minutes)
   • Begin the lesson by asking the students if they know what division is.
   • Explain that division is a mathematical operation that helps us share or distribute things equally.
   • Give examples of division in everyday life, such as sharing candies or dividing a pizza into equal slices.
2. Review of Telling Time (10 minutes)
   • Review the concept of telling time using an analog clock or watch.
   • Ask students to identify the hour and minute hands on the clock and explain their functions.
   • Practice reading and writing different times on the clock, including both hours and minutes.
3. Division of Hours (15 minutes)
   • Explain that sometimes we need to divide a certain number of hours by a whole number.
   • Write a division problem on the board, such as 12 ÷ 3, and explain that it means dividing 12 hours into 3 equal parts.
   • Demonstrate how to solve the problem step by step, using manipulatives or drawings if necessary.
   • Provide more examples of division problems involving hours and guide the students in solving them.
4. Division of Minutes (15 minutes)
   • Explain that we can also divide minutes by a whole number, just like we did with hours.
   • Write a division problem on the board, such as 60 ÷ 5, and explain that it means dividing 60 minutes into 5 equal parts.
   • Demonstrate how to solve the problem step by step, using manipulatives or drawings if necessary.
   • Provide more examples of division problems involving minutes and guide the students in solving them.
5. Application and Practice (15 minutes)
   • Distribute worksheets with division problems related to time.
   • Instruct the students to solve the problems independently, using the division skills they have learned.
   • Circulate around the classroom to provide assistance and monitor their progress.
   • Review the answers as a class and address any questions or misconceptions.
6. Real-Life Problem Solving (10 minutes)
   • Present a few real-life scenarios that involve dividing hours and minutes by a whole number.
   • For example, “If a movie is 120 minutes long and you want to watch it in 4 equal parts, how long will each part be?”
   • Encourage the students to think critically and apply their division skills to solve the problems.
   • Discuss the solutions as a class and highlight the importance of division in everyday life.
7. Conclusion (5 minutes)
   • Summarize the key points covered in the lesson, emphasizing the concept of division and its application in dividing hours and minutes by a whole number.
   • Allow time for any final questions or clarifications.
   • Provide positive feedback and praise for the students’ efforts and participation.

Extension Activity: - Divide the students into pairs or small groups and ask them to create their own division problems related to time. They can then exchange problems with another group and solve them.

Assessment: - Monitor students’ participation and engagement during class discussions and activities. - Review completed worksheets to assess their understanding of division of hours and minutes by a whole number. - Observe students’ problem-solving skills during the real-life problem-solving activity.
