STEP-BY-STEP SOLVED EXAMPLES

Example 1: 148 × 1

In this problem, we apply the identity property of multiplication, which states that any number multiplied by one remains the same.

• Step 1: Multiply the ones: 1 × 8 = 8.
• Step 2: Multiply the tens: 1 × 4 = 4.
• Step 3: Multiply the hundreds: 1 × 1 = 1.
• Result: 148

Example 2: 211 × 9

• Step 1: Multiply the ones: 9 × 1 = 9.
• Step 2: Multiply the tens: 9 × 1 = 9.
• Step 3: Multiply the hundreds: 9 × 2 = 18.
• Result: 1,899

Example 3: 631 × 6

• Step 1: Multiply the ones: 6 × 1 = 6.
• Step 2: Multiply the tens: 6 × 3 = 18. Write the 8 in the tens place and carry the 1 to the hundreds place.
• Step 3: Multiply the hundreds: 6 × 6 = 36. Add the carried 1 to get 37.
• Result: 3,786

TEACHER & PARENT TIPS

To support students, suggest they use the expanded form method (e.g., 631 is 600 + 30 + 1) to understand how partial products combine to create the final answer. If a student struggles with column alignment, using graph paper can help them keep place value columns straight. Encourage students to estimate their answers first; for instance, in problem 4 (612 × 6), estimating 600 × 6 = 3,600 helps them verify if their calculated answer of 3,672 is reasonable.
