Learning Objectives

Students will be able to multiply whole numbers of up to four digits by one-digit and two-digit whole numbers, using strategies based on place value.


Introduction (5 minutes)

  • Begin this lesson by reviewing place value. Write a five-digit number on the board. Have students come to the board and identify each number's place value.
  • Tell students that today they are going to use what they know about place values to help them calculate multi-digit numbers.
  • Write a two-digit by one-digit multiplication problem on the board.
  • Have students raise their hands and work on solving the problems to show you if they have previous experience with multiplying multi-digit numbers like the one on the board.
  • Explain to them that it is very doable as long as they know the value of the two single numbers, place value, and a strategy called regrouping.

Explicit Instruction/Teacher Modeling (25 minutes)

  • Remind students of basic multiplication facts by using Multiply! as a quick review.
  • Review the answers by using the answer key.
  • Offer students suggestions for this quick assignment by reviewing the patterns found in each row.
  • Use the table to work problems in which double digit numbers are multiplied by single digit numbers using problems from the Multiplication with Regrouping or Mammoth Multiplication Problems worksheets.
  • Next use problems from the Double Digit Multiplication worksheet to use place value when multiplying multi-digit numbers by two-digit numbers.

Guided Practice/Interactive Modeling (20 minutes)

  • Have students find a partner.
  • Pass out the Math-Go-Round (Hard) game and scratch paper for completing their calculations.
  • Read the instructions for the game to students. Set a time limit for each calculation or for the entire game if you would like.
  • Ask students if they have questions.
  • Have students work in pairs to complete the calculations.
  • Allow the last 2-4 minutes to discuss challenges.

Independent Working Time (20 minutes)

  • Pass out the Math-Go-Round (Expert) game and scratch paper for completing their calculations to students.
  • Tell students that they will work alone to complete the game board.
  • Make this a timed assignment if you would like.
  • Remind students to use place value when calculating multi-digit numbers by two-digit numbers.
  • If students get stuck, advise them to go to the next calculation.
  • Allow time to review the challenging problems (as determined by the students) and answers after this assignment.



  • Enrichment: Advanced students could create a children’s book with step-by-step instructions for multiplying multi-digit numbers by one and two-digit numbers. They could also complete the Multiplying Multi-Digit Numbers worksheet which requires them to multiply several six-digit numbers by two-digit numbers and even multiply by three-digit numbers.
  • Support: Students who need extra support could create their own more simplistic problems and answer them.

Technology Integration


Assessment (20 minutes)

  • Use the Multiplication Mischief worksheet to assess students' understanding of the lesson.
  • Remind students that they must use place value to answer each question.

Review and Closing (5 minutes)

  • Review place value and the multiplication chart.
  • Write an equation on the board and have students work the problem out with you on the whiteboard.
  • Remind students that it is important for them to understand multiplication and place value.
