Students Learn the Box Method for Multiplying Two-digit Numbers Through Guided and Independent Practice.

Title: Box Method Multiplication

Objective: By the end of this lesson, students will be able to use the box method to multiply two-digit numbers.

Materials:

• Whiteboard or chart paper
• Markers or colored pencils
• Grid paper or blank paper
• Pencils
• Two-digit number cards (e.g., 24, 35, 48, etc.)

Introduction (5 minutes):

1. Begin the lesson by asking students if they know any methods to multiply two-digit numbers.
2. Write down their responses on the whiteboard or chart paper.
3. Explain that today, they will learn a new method called the "box method" that can help them multiply two-digit numbers easily and accurately.

Procedure (20 minutes):

1. Distribute grid paper or blank paper to each student.
2. Write a two-digit number on the board (e.g., 24) and ask students to write it at the top of their paper.
3. Explain that the box method involves breaking down the two-digit numbers into their tens and ones places.
4. Draw a large box on the board and divide it into two smaller boxes, one for the tens place and one for the ones place.
5. In the tens place box, write the number in the tens place (2) and in the ones place box, write the number in the ones place (4).
6. Ask students to do the same on their papers.
7. Now, draw two more boxes below the first set of boxes, one for the tens place and one for the ones place.
8. In the tens place box, write the number in the tens place (2) and in the ones place box, write the number in the ones place (4).
9. Ask students to do the same on their papers.
10. Instruct students to multiply the numbers in each box vertically (2 x 2 = 4 and 2 x 4 = 8).
11. Write the products in the corresponding boxes on the board and ask students to do the same on their papers.
12. Finally, add up the products in each column (40 + 8 = 48) to find the final answer.
13. Write the final answer on the board and ask students to compare their answers with the board.

Guided Practice (10 minutes):

1. Give each student a two-digit number card.
2. Instruct them to use the box method to multiply the number on their card with a number you provide.
3. Walk around the classroom to provide assistance and check for understanding.
4. After a few minutes, ask a few students to share their answers and explain their thinking.

Independent Practice (10 minutes):

1. Distribute a worksheet with various two-digit multiplication problems.
2. Instruct students to solve the problems using the box method.
3. Circulate the classroom to provide support and check for accuracy.
4. Collect the worksheets at the end of the activity.

Conclusion (5 minutes):

1. Review the box method and its steps with the students.
2. Ask students to share any challenges they faced while using the box method.
3. Address any misconceptions or difficulties.
4. Summarize the lesson by emphasizing the usefulness of the box method for multiplying two-digit numbers.
5. Encourage students to practice using the box method at home to reinforce their understanding.
