Students will have fun as they explore the world of probability using dice in this introductory math lesson.
Students will identify the probability of outcomes using a die.
Introduction (15 minutes)
- Explain to students that they will be learning about a statistic called probability.
- Write the word "Probability" and the definition, the likelihood that something will happen, on the board.
- Hold up a die and ask the students how many numbers are on the die.
- Roll the die a few times and record the numbers rolled on the board.
- Lead a conversation with the students to discuss the probability of how likely it is to roll a number until students realize the probability of rolling any number on a die is 1/6.
Explicit Instruction/Teacher Modeling (5 minutes)
- Display the Roll the Die! worksheet for the class to see.
- Hand out the Roll the Die! worksheets to your class and read the directions.
- Hand out the dice.
- Model to the students how to properly roll the die so that it stays on their desks and explain any other expectations you have for their handling of dice.
- Model to the students how to record the tally marks on their sheet by rolling the die and tallying the marks on the display.
Guided Practice/Interactive Modeling (20 minutes)
- Instruct the students to complete the table on the Roll the Die! worsheet.
- Walk the room and monitor students and assist as needed.
- Once students have finished rolling, ask for volunteers to share the amount of times they rolled the die for each number and their total number of rolls.
- Show students how to convert their number of rolls for each number and the total number of rolls into a fraction.
- Instruct students to complete the Roll the Die! worksheet.
Independent Working Time (10 minutes)
- Hand out the Heads or Tails worksheet for the students to independently complete.
- Walk around the room to assist students as necessary.
- Enrichment: Challenge advanced students to create a graph of the Roll the Die! table on a separate piece of graph paper.
- Support: Allow students who need support to work in pairs or in a group during independent work time.
- Use the completed Roll the Die! and Heads or Tails worksheets as an informal assessment.
Review and Closing (10 minutes)
- Display the Heads or Tails worksheet and go through the worksheet together with the class or have students volunteer answers after independent work time.
