2-Digit x 2-Digit — Multiply & Divide Pathway

Multiplying two 2-digit numbers

  • Use the column method with two rows of working.
  • First multiply by the ones digit.
  • Then multiply by the tens digit (add a zero placeholder).
  • Finally add the two rows together.

Example: 23 x 14

  1. Step 1: 23 x 4 = 92 (ones row).
  2. Step 2: 23 x 10 = 230 (tens row).
  3. Step 3: Add: 92 + 230 = 322.
  4. Answer: 23 x 14 = 322.

Your turn

  • Try: 31 x 12.
  • 31 x 2 = 62.
  • 31 x 10 = 310.
  • Add: 62 + 310 = 372.

Common Mistakes to Avoid

  • Forgetting the zero placeholder for the tens row. The second row must start one place to the left.
  • Adding the rows incorrectly. Line up the digits carefully before adding.

Real-Life Example

A school has 23 classrooms with 14 chairs in each. 23 x 14: 23 x 4 = 92, 23 x 10 = 230, 92 + 230 = 322 chairs.

Extra Support Hints

  • Write a zero at the end of the second row to remind you it is the tens row.
  • Check the answer is sensible: 23 x 14 is roughly 20 x 15 = 300.
