Math 9 Stats and Probability – Residential Schools

Grade ̸ Subject: Mathematics 9- Stats and Probability

Topic: This lesson will explore probability and statistics with respect to Residential Schools and how probability and data are not always accurate.

Outcomes: Indicators:
Outcome: SP9.3Demonstrate an understanding of the role of probability in society. [C, CN, R, T] b. Analyze the meaningfulness of a probability against the limitations of assumptions associated with that probability.



Prerequisite Student Learning: Students should have an understanding of how to calculate experimental probability.

Set: (approximately 10 minutes)

  • Draw a T chart on the board, one side has Taken Away and the other side has Forced Upon.

Taken away- language, hair, name, clothing, religion

Forced upon- Christianity, English, European beliefs,

  • Brainstorm with students what they seen in the exhibit that fits in each category.

Development: (approximately 100 minutes)

  • Explain how we adapted the Aboriginal game Lahal to create our own game
  • Explain rules of game (see page )
  • Have students play game and fill in data sheet (see page )
  • Discuss punishment for specific activities in the game:

Disobedience= no food or water for a day, beating, extra garden work

Failing a test= no food for a day

Speaking native language x1= no supper

Speaking native language x2= no supper, beating

Speaking native language x3= no food or water for a day, beating, extra garden work

Not working hard enough= 4 hours extra work

Going off by yourself= kneeling alone on rock floor where everyone can see

Wetting the bed= wore the soiled sheet overtop of your head in front of everyone

  • Discuss how if you had more than 5 punishments you would not survive
  • Discuss results as a whole class
  • Have students calculate specific probabilities in their data (such as: probability of praying, probability of speaking native language, probability of survival etc.)
  • Have students research actual statistics regarding survival rates and treatment of students at residential school
  • Students bring findings to class and in groups compare findings to the probability found in the game
  • Have students present results to the class

Closure: (approximately 10 minutes)

  • Discuss how probability is not always accurate and how data can be skewed
  • Do a 3-2-1, 3 things they learned, 2 things they have a question about, 1 thing they want the instructor to know

Materials and Aids:

  • Cards for the games
  • Worksheets
  • Game Rules

Class Management:

  • Have groups chosen ahead of time
  • Walk around to keep students on task

Assessment and Evaluation

  • Assess:
    • Completion
    • Accuracy
    • Reliable resources
    • Presentation- attitude, organization, group work

**Mark a tally beside the behaviour that corresponds with each paper** YOU draw

Speaking their Native language once
Speaking their Native language twice
Speaking their Native language three times

Going off By Themselves





Game Rules

  1. The person with the most letters in their first name goes first, then the order continues going clockwise around the table.
  2. On their turn, the person selects a behaviour card from the middle and records tally on the worksheet.
  3. Discuss whether or not that behaviour would result in a punishment; if so, what would that punishment be?
  4. Once recording and discussion are completed proceed to the next turn.
  5. Repeat until each individual has taken ten turns.
