  3. I will multiply up to a three-digit number by a one-digit number. Main Idea/Vocabulary

  4. Estimate48 × 6 50 × 6 = 300 4 48 6 × 8 Two-Digit and Three-Digit Numbers Find 48 × 6. Step 1 Multiply the ones. Step 2 Multiply the tens. 4 48 6 × 8 28 6 × 8 = 48 ones 6 × 4 = 24 tens 24 + 4 = 28 tens Answer: So, 48 × 6 = 288. Example 1

  5. A B C D Find 73 × 5. • 350 • 362 • 365 • 735 Example 1

  6. Estimate450 × 8 450 × 10 = 4,500 Two-Digit and Three-Digit Numbers A theater can seat 450 people for each show. If the theater fills for 8 shows, how many people attend in all? Step 1 Multiply the ones. Regroup if necessary. 450 × 8 0 8 × 0 = 0 ones Example 2

  7. 450 450 × × 8 8 00 0 Two-Digit and Three-Digit Numbers Step 2 Multiply the tens. Add any new tens. Regroup if necessary. 4 0 8 × 5 = 40 tens Step 3 Multiply the hundreds. Add any new hundreds. Regroup if necessary. 4 8 × 4 = 32 hundreds 36 32 + 4 = 36 hundreds Answer: So, 3,600 people can attend 8 shows. Example 2

  8. A B C D An auditorium seats 625 people for each show. If the auditorium fills for 7 shows, how many people attend in all? • 4,125 people • 4,375 people • 4,750 people • 5,150 people Example 2
