Data Speaks: Statistical Persuasion Workshop ✨ multi-grade cross-curricular
Teacher: Demo Teacher | Grade: 4, 5 | Subject: Reading/ELA, Science | Duration: 60 minutes
📝 Description: Students analyze survey data to create graphs and write persuasive paragraphs using statistics to support their arguments.
Standards
- 4.MD.B.4 - Make a line plot to display a data set of measurements in fractions of a unit
- 5.MD.B.2 - Make a line plot to display a data set of measurements in fractions of a unit
- W.4.1 - Write opinion pieces on topics or texts, supporting a point of view with reasons and information
- W.5.1 - Write opinion pieces on topics or texts, supporting a point of view with reasons and information
Learning Objectives
Students will be able to:
- Create accurate bar graphs and line plots from survey data using graph paper
- Calculate percentages and fractions from data sets to use as evidence
- Write persuasive paragraphs incorporating specific statistics and data
- Identify the strongest statistical evidence to support an argument
- Present data-driven opinions in appropriate written formats (4th grade: paragraphs, 5th grade: opinion articles)
Materials Needed
- Graph paper (2 sheets per student)
- Computers or tablets (1 per student for final writing)
- Pre-collected survey data sheets (classroom favorites: snacks, recess activities, book genres)
- Calculators (1 per pair)
- Persuasive writing anchor chart
- Data analysis worksheet template
Lesson Structure
Opening (5 minutes)
Display sample survey results on board: "20 out of 25 students prefer pizza over hamburgers." Ask: "How could a pizza company use this information to convince our principal to serve more pizza?" Introduce the goal: using data to persuade others.
Main Activity (50 minutes)
Step-by-step instructions:
- Data Distribution & Analysis (8 minutes): Give each student survey data from three classroom polls (favorite snack, preferred recess activity, best book genre). Have students work in pairs to identify the "winner" in each category and calculate basic fractions (15 out of 25 = 15/25 = 3/5).
- Graph Creation (12 minutes): Students choose their strongest data set and create a bar graph on graph paper. Model proper labeling: title, axis labels, and scale. Circulate to ensure accuracy and neat presentation.
- Statistical Evidence Gathering (8 minutes): Students convert their data into persuasive statistics. Teach key phrases: "3 out of 4 students," "75% of classmates," "the majority chose." Have students write 3-4 statistical statements about their data.
- Persuasive Planning (7 minutes): Students select their position (supporting the winning choice) and outline their argument. Provide sentence starters: "The data clearly shows..." "According to our survey..." "Statistics prove that..."
- Differentiated Writing (12 minutes): 4th graders write persuasive paragraphs with topic sentence, three supporting details using statistics, and conclusion. 5th graders write structured opinion articles with introduction, body paragraphs using data, counterargument acknowledgment, and conclusion.
- Digital Composition (3 minutes): Students transfer their writing to computers, adding their graphs as visual support. Show how to insert simple tables or reference their hand-drawn graphs.
Closing (5 minutes)
Students share one powerful statistic from their writing with a partner. Highlight how data makes arguments stronger and more convincing than opinions alone.
Quick Check: What makes a statistic convincing? How did graphs help your argument? Name one way data is better than just stating your opinion.
Formative Assessment
During the lesson, look for:
- Accurate graph construction with proper labels and scaling on graph paper
- Correct calculation of fractions and percentages from raw survey data
- Integration of specific statistics within persuasive sentences rather than just listing numbers
Differentiation Strategies
Support for Struggling Students:
- Provide pre-made graph templates with scales already marked
- Give sentence frames: "__ out of __ students chose __, which means __"
- Pair with stronger math students for fraction/percentage calculations
Challenge for Advanced Learners:
- Calculate and compare data from multiple surveys to find correlations
- Create double bar graphs comparing two related data sets
- Write counterarguments acknowledging opposing data and refuting it
ELL/ELD Support:
- Provide vocabulary cards with key terms: survey, data, majority, percentage, evidence
- Use visual math models to show fraction-to-percentage conversions
- Allow native language discussion during partner work for data analysis
