Part-to-Whole
Building from prior knowledge
Concrete to abstract
Discovery learning using relevant data
Real-world examples
Real-World Examples—Polls • What’s your favorite…
• Movie?
• Band?
• How many…
• Siblings?
• Pets?
• Categorize the class
• Hair color
• Height
Multiple Representations• Class measurements as histograms
• Compare and contrast with bar graphs
• Class measurements as stem-and-leaf plots
• Introduce mode, median, range, and IQR
• Box plots as performance assessment
Data Analysis Descriptives
Measures of central tendency
Measures of spread
General distributions of data
Statistically specific language
Word Walls• Students discover concept
independently• Teacher defines the new concept
using statistically specific language• Students then redefine specific
statistical terms using student-friendly language
• Terms are displayed• After term introduction, students
must practice using specific vocabulary vs. general
• “Could you be more specific?”• “Do you see a Word Wall term
that could be used here?”
