**Lesson Plan of Multiplication of 2-digit by 1-digit Numbers**

**Subject Mathematics**

**Grade III**

**Students` Learning Outcomes**

- Multiply 2-digit numbers by 1-digit numbers.

**Information for Teachers**

- To multiply a 2-digit number by a 1-digit number, first multiply the numbers at ones place, then multiply the number with the number at tens place.

- While teaching the lesson, also consult textbook where and when applicable.

**Material / Resources**

Writing board, chalk/marker, duster, chart (having steps of multiplication of 2-digit numbers), Mathematics textbook

**Introduction**

- Write on the board:

- Call the students one by one to solve the questions on the board.
- Check the work and appreciate them.
- Write on the board:

- Ask the students, can you solve this question?
- Collect their feedback and display the following chart in front of the class:

- Explain the steps to the students one by one with the help of example.
- Solve the question on the board with the help of students.
- Tell the students that let us practice more questions.

**Development**

**Activity 1**

- Write the following question on the board: Multiply 43 by 2.
- Ask the students, what will you do first to solve this question?
- Collect their feedback and tell them that first write it in vertical form.

- Call any student to solve the question on the board.
- Check the work and correct the mistake if any.
- Write some more questions on the board (without carrying) and ask the students to solve in their notebooks.
- Observe their work and guide where needed.

**Activity 2**

- Write the following question on the board: find the product of 24and 3.
- Ask any student to write it in question form on the board.
- Ask the students to first multiply 3 and 4.
- Collect their answer and tell the students that in number ‘12’, there are ‘2 ones’ and ‘1 ten’ so we write ‘2’ under the ones place and carry 1 ten above the tens place.
- Then ask to multiply 3 and 2 and add 1 in it.
- Tell the students that write ‘7’ below the tens place.
- Write the correct answer on the board.

- Write some more questions on the board and ask the students to solve in their notebooks.

**Sum up / Conclusion**

- Revise the concept with the help of chart used in Activity 1.

**Assessment**

- Write the following question on the board:

- Ask the students to solve these in their notebooks.

**Follow up**

- Count the number of chairs at your home.
- Count the number of legs of a chair.

- Ask the students to solve the questions given in the textbook.

The Center for Cold-Formed Steel Buildings (CCFSS) was established at the University of Missouri-Rolla (now Missouri College of

Science and Systems) in May 1990 under an initial grant received from

the Usa Metal and Metallic Start. Above the ages,

the Center’s sponsorship provides harvested to include:

Cold-Formed Material Engineers Initiate, Steel Engineering

Connection, Roof-rack Producers Initiate, Simpson Strong-Tie,

Material Deck Institute and Metal Framing Marketplace Connection. In 2000, the Center was initially renamed

for its Founding Director, Dr. Wei-Wen Yu.

The Centre is dedicated to furthering the field of cold-formed steel and hosts

continuing education events such as the Wei-Wen Yu Essential Custom made Conference on Cold-Formed Metallic Structures, which has taken place every other year since 1971.

Top doctors, fitters, companies and educators who possess employed in exploration, design, produce and the make

use of of cold-formed material people collect at

this convention to present specified posts of their current findings.
