Multiply a two-digit number by a two-digit number

Understanding Place Value

• Two-digit numbers have a tens place and a ones place.
• Example: In the number 34, 3 is in the tens place (representing 30), and 4 is in the ones place.

Basic Multiplication Facts

• Ensure students are comfortable with basic multiplication facts (e.g., 1×1 to 10×10).
• This knowledge will help them when multiplying larger numbers.

Steps for Multiplying Two-Digit Numbers

• Step 1: Multiply the ones digit of the second number by the first number.
  • Example: For 34 x 12, multiply 2 (ones digit of 12) by 34.
  • Calculation: 34 x 2 = 68.
• Step 2: Multiply the tens digit of the second number by the first number, and remember to add a zero at the end.
  • Example: Now multiply 1 (tens digit of 12) by 34.
  • Calculation: 34 x 10 = 340.
• Step 3: Add the results from the two multiplications.
  • Example: Add the results from steps 1 and 2.
  • Calculation: 68 + 340 = 408.
• Therefore, 34 x 12 = 408.
