Introduce your students to multiplying multi-digit numbers with this lesson that gives them plenty of practice and has them play a game with a partner that makes the lesson fun!
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.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

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.
Beginning
Provide student-friendly definitions in students' home language (L1) and English (L2), for the following terms: "place value," "digit," "regrouping," "multiply." Include an image or example for each word.
Intermediate
Give students a chance to solve the two-digit by one-digit multiplication problem with a partner before sharing their solution with the whole group.
