School Boards Lesson Title: Probability Lesson 1 School Date Grade(s) Learning Goal (Curriculum Expectations) demonstrate, through investigation, an understanding of fairness in a game and relate this to the occurrence of equally likely outcomes Lesson Components Before Have the students brainstorm all the words they know about probability. As they come up with the words plot them on a probability continuum line from impossible to certain. Discuss that some words may mean the same thing (fair chance/equally likely). Anticipated Student Responses Also discuss that probability means chance; you can have a discussion regarding the difference between skill and chance. During Have the students write 5 sentences to show that they know the meaning of the words: Certain/always/100% Likely/probably Equal chance/ maybe/ 50% chance 50/50 /Equally likely/ Unlikely/ improbable/ uncertain Impossible/never 0% chance After (Consolidation) Have students share their sentences to ensure they have a strong understanding of the words and how they can be used. Have a class discussion about words that are used incorrectly. Talk about what does fair mean? Not always ½ and ½ but also 1/3, 1/3, 1/3 After (Highlights and Summary) Co-create a word list for all the words that students will need to know for probability. Pick some sentences to put on the anchor chart for students to refer to the words and their meaning. After (Practice) Michael has 8 white shirts and 2 blue shirts in a bag. He takes 1 shirt from the bag without looking. Which best describes the chance that the shirt Michael takes from the bag is blue? Explain your thinking. Impossible Unlikely Likely Certain
