Detailed Timing Breakdown
TimePhaseWhat HappensInstructor Action
0โ€“8 min PLAN Students choose their data question and record it on the planner. Must be answerable by surveying classmates today. Model a strong question ("How many minutes do you read each day?") vs. a weak one ("Do you like stuff?"). Circulate to approve questions before collecting begins.
8โ€“25 min COLLECT Students survey at least 10 classmates, recording tally marks or numbers on their planner. Keep students moving. Redirect anyone stuck โ€” suggest a simple question they can survey right now. Timer visible. Signal at 20 min to wrap up and return to seats.
25โ€“35 min ORGANIZE Students tally and total their data, identify the most and least common responses, calculate range or mean if applicable. Check totals add up. Prompt: "What's the highest value? Lowest? Is there a pattern?"
35โ€“47 min VISUALIZE Students choose and build one chart (bar, line, or dot plot). Add title, axis labels, and scale. Remind: bar chart for categories, line graph for time, dot plot for spread. Check that Y-axis starts at 0 and has a title.
47โ€“57 min WRITE Students write 3โ€“4 sentences: one claim, one evidence sentence, one interpretation, one connection. Sentence frames on board. Circulate to ensure each sentence references the actual data numbers.
57โ€“60 min SHARE Gallery walk or 3-volunteer share-out. Audience gives one compliment using the sentence frame: "I noticed your data shows ___." Celebrate all efforts. Post work on wall if time permits.
Sample Strong Student Questions
Numerical Data
  • How many hours of sleep did you get last night?
  • How many books have you read this month?
  • How many minutes do you spend outside each day?
  • How many siblings do you have?
Categorical Data
  • What is your favorite school subject?
  • How do you get to school?
  • What is your favorite type of music?
  • What is your favorite season?
Avoid These
  • Yes/no questions (only 2 data points)
  • Questions with too many options (>6)
  • Questions requiring memory from weeks ago
  • Private or sensitive topics
Data Story Writing Frames โ€” Post on Board
Sentence Frames for the Write Phase

The most common answer was ___, chosen by ___ out of ___ people.
I was surprised that ___ because I expected ___.
My data shows that most people ___, which means ___.
If I could survey more people, I would want to find out ___.

Quick Chart Choice Guide
Choose a Bar Chart When...
  • Data has distinct categories (favorite food, transport type)
  • You want to compare amounts across groups
  • Numbers don't flow over time
Choose a Line Graph When...
  • Data changes over time (daily steps, weekly reading)
  • You want to show a trend
  • X-axis values are ordered numbers
Choose a Dot Plot When...
  • Numerical data with a relatively small range
  • You want to see clusters and spread
  • Each individual value matters
Chart Checklist
  • Title that describes the data
  • X-axis and Y-axis labeled
  • Y-axis starts at 0
  • Scale is consistent
  • All bars/points are accurate
