Probability and Statistics
We will:• Explore the connection of concepts within a
grade and the progression of concepts between grades
• Discuss various teaching strategies
• Engage in various activities that we might use in the classroom
Today’s Goals
Statistics and Probability
Students view statistical reasoning as a 4 step process· Formulate questions that can be answered with data · Design and use a plan to collect relevant data· Analyze the data with appropriate methods· Interpret results and draw valid conclusions from the data that relate to
the questions posed.

• Discuss what a statistical question is and give examples.
• Discuss various examples and non examples
• Have students work through a sorting activity in which they separate statistical and non-statistical questions
• Have students come up with their own real life situations and create their own statistical and non statistical questions
• Share out questions as a class and sort into the two categories
