Title: Multiplications

Grade: 2-a Lesson: S4-L2

Explanation: The best way to understand multiplications is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Step: 1a

Multiply 6 x 24

Write the largest number or the multiplicand on the top side and one digit number or the multiplier on the bottom.

$1a$

Explanation: Arrange the numbers vertically.

Step: 1b

Start by multiplying the digit in the one’s place of the bottom number by the digit in the one’s place of the top number,i.e., \$6 \times 4 = 24\$.
Write down 4 and carry over 2 to the tens place.

$1b$

Explanation: Start by multiplying the ones place, i.e., 6 x 4 = 24. Then carry over 2 to the preceding ten’s column and write 4 below the one’s column.

Step: 1c

Now, multiply the number in the tens place by 6,i.e., 6 × 2 = 12 tens.
Finally, add 2(carry over) + 12= 14. Write 14 at the tens place.
Therefore,6 x 24 = 144.

$1c$

Explanation: In this step, multiply the digit at the tens place by 6. 6 × 2 = 12 tens.Now, 12 + 2(carry over) = 14 tens. Hence, 6 x 24 = 144.
