Students will "roll" to this quick game and "slap out" multiplication facts to reinforce multiplication skills and beat their own scores!

### Learning Objectives

Students will be able to recall a variety of multiplication facts based on repetition and peer support.

## Lesson

### Introduction (5 minutes)

• Explain to your students that they will refresh their multiplication skills with a game.
• Have volunteers call out various multiplication facts that they know to get warmed up.

### Explicit Instruction/Teacher Modeling (10 minutes)

• Take the face cards out of the decks before playing the game.
• Put your students into groups.
• To determine who starts the game, have each student roll the dice. The person with the largest number will go first.
• Instruct someone in each group besides the roller to begin the timer as soon as the student rolls for his turn.
• When the first student rolls the dice, have him write down the number on his sheet. Then, direct him to count out the number of cards that the dice lands on and flip the last card face up. For example, if a student rolls a dice and it lands on 5, the fifth card will be flipped up to reveal the number.
• Then, instruct the student to multiply the dice number and the card number together. Ask him to write down the equation and say the product aloud to the group.
• Have the timekeeper stop keeping time.

### Guided Practice/Interactive Modeling (10 minutes)

• Instruct your students to continue until the first two rows are filled for each student in a group.
• Remind someone in each group to keep time, and make sure that your students record their numbers from the dice and cards on their worksheets.

### Independent Working Time (5 minutes)

• Have your students work independently on the same activity, and encourage them to beat their time.
• Have them practice at least ten times so that they can improve their speed and memory.

## Extend

### Differentiation

• Enrichment: Keep the face cards in the deck for more advanced students. In this modified version of the game, the King triples the next number, the Queen doubles the next number, and the Jack represents a zero.
• Support: Give your students a printable multiplication chart to refer to.

## Review

### Assessment (5 minutes)

• Use the assessment sheet to measure how your students are doing.
• Write down additional comments in the comment box. Circle W if a student needed assistance or circle WO if a student did not need assistance doing the multiplication.

### Review and Closing (5 minutes)

• Place a blank Roll It and Slap It worksheet on display.
• Play the game as a class to review.
• Have one volunteer roll the dice, flip the card, and multiply it quickly to fill in the worksheet. Keep time for this student.
• Instruct that first volunteer to be the timekeeper for the next volunteer, and continue this until the worksheet is complete.
