### Lesson plan

# Domino Multiplication

#### Learning Objectives

Students will practice multiplying by 2's.

#### Introduction

*(5 minutes)*

- Tell your students that they will practice multiplying by 2's using a fun worksheet and playing a game.

#### Explicit Instruction/Teacher modeling

*(5 minutes)*

- Show students the dominoes.
- Explain to them that the dots on the left side and right side of the domino represent a number. For example, three dots represents the number three and so on.
- Tell your students that they will be adding up all the dots on one domino (left and right side) and multiplying that number by 2.

#### Guided Practice

*(10 minutes)*

- Pass out the Double Domino multiplication worksheet.
- Have your students add up the dots on each domino, multiply by 2, and write down the answer on their worksheets.
- When the worksheet is completed, group the students into pairs of two.
- Explain that they will be playing the game of dominoes with a twist!
- Pass out five dominoes facedown to each student.
- Direct one partner to go first, place down a domino, add up the total, and multiply by 2.
- Instruct the second partner to check the answer of the other student, and then have that partner take her turn.
- Have the second partner place a domino down that matches the end of the first domino. For example, if the first partner's domino is a 2 on the left side and a 3 on the right side, the 2nd partner needs to place a 3 down to match the 3.
- Ask that student to add up the total and multiply by 2.
- If one of the students doesn't have a match to the domino, have her draw one from a pile. If there still isn't a match, the turn is over. If there is a match, the student plays the domino.

#### Independent working time

*(20 minutes)*

- Direct students and their partners to play the domino multiplication game until there are no more dominoes.
- If there is time, have the students play the game again.

#### Differentiation

**Enrichment:**Instruct your students to multiply their domino sums by a different number other than 2, such as a 3, depending on their learning needs.**Support:**Give your students physical blocks to count out their multiplication problems. For example, if the question is 2 x 7, then have these students count out two rows of seven blocks and add them up.

#### Assessment

*(5 minutes)*

- Walk around during the domino game, and check to make sure that your students are completing the activity.

#### Review and closing

*(5 minutes)*

- Have your students come back together as a class.
- Write an example multiplication problem on the board.
- Ask your students to determine the answer.
