Introduction

• Work on the board:

• Ask the students, how can we solve this question mentally?
• Collect their feedback and tell them that with the help of multiplication table, we can solve it.
• Ask the students to say multiplication table of 4 loudly.

• Ask the students to stop the table, when the number ‘20’ comes.
• On completion, write on the board: 4 times 5 = 20, 4 x 5 = 20

• So the required answer is 5.

Development

Activity 1

• Write on the board:

• Ask any student to come in front and read the table of 3 loudly until the number ‘24’ comes.

• On completion, tell the students that the number ‘24’ comes at 8.
• So 8 is our required answer.
• Write the answer on the board.

• Repeat this activity for more questions.
• Involve maximum students in this activity.
• Pay special attention to the slow learners.

Sum up / Conclusion

• Revise the multiplication tables up to 10.

Assessment
