Today’s Goals
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
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.

Statistical Question
• 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

Introduce the need for measures of variability
Two sets of grades on math tests
Student A: 29, 45, 50, 70, 98, 99, 99
Student B: 64, 67, 69, 70, 72, 73, 75
Who is the better student?
