0–5🎯 HookShow Graph 1. Ask: "Tell me one thing you know just from looking." Take 5 responses.
5–13📖 LessonReading vocabulary: most, least, same, compare, how many more. Teacher models each with Graph 1.
13–28🎮 Group WorkGroups of 2–3 answer 4 questions about Graph 2. Teacher circulates.
28–38💬 Share + DiscussClass discusses answers to Graph 2 questions. Introduce Graph 3 — students answer independently.
38–46✍️ WorksheetStudents complete worksheet using the 3 provided graphs.
46–50🧠 Brain Break + CloseStand-up comparison break. Preview Session 7: designing your own survey!
Reading strategy: Always point to the specific bar while asking the question. "Look at THIS bar — how tall is it? Find that number on the scale." Physical pointing bridges the visual and the question.
📦 Materials Needed
3 bar graphs printed or projected (use worksheet graphs) Pencils Worksheets (1 per student) Sentence frame cards (optional — print from below)
💡 Make the 3 graphs large enough to be seen from the back of the room. If projecting, keep them up during group work time.
📚 Key Vocabulary
Most — the category with the highest bar / biggest number
Least — the category with the lowest bar / smallest number
Same — two bars that are the same height / equal numbers
Compare — look at two things side by side to find differences
How many more — find the difference by subtracting the smaller from the larger
💬 Sentence Frames
"The most popular ___ was ___ with ___ votes."
"The least popular ___ was ___ with ___ votes."
"___ got ___ more votes than ___."
"___ and ___ got the same number of votes."
💬 Discussion Questions + Teacher Notes
  • "Which bar is the tallest? How do you know?"
    → Students should point AND read the scale. "I can see it's the tallest, and the scale shows it reaches 8." Train them to verify visually AND numerically.
  • "How many MORE votes did ___ get than ___?"
    → This requires subtraction. Guide: "Find the number for each, then count up from the smaller to the bigger." Use fingers if needed. "8 minus 5 — how many steps from 5 to 8? 1, 2, 3 — three more."
  • "What if two bars are the same height — what does that tell us?"
    → That two things got exactly the same number of responses. This is a valid and interesting finding. "Is that surprising? Why or why not?"
  • "Can you find something interesting in this graph that I didn't ask about?"
    → Open-ended reading. Students may notice the gap between first and last place, that three categories are close together, or that the total adds to a particular number. All valid.
  • "If we added one more vote to the least popular category — would it change the graph? How?"
    → Yes — the bar would go up one grid square. Reinforces that bar height = number of votes, and any change in data changes the graph.
🎮 Three Sample Graphs for This Session
Use these three graphs for the whole session. They are also printed on the student worksheet.
Graph 1 — Favorite Pets (for teacher modeling):
Dog: 8 · Cat: 5 · Fish: 3 · Bird: 2 · Rabbit: 5
Graph 2 — Favorite Fruits (for group work):
Apple: 6 · Banana: 4 · Strawberry: 9 · Mango: 4 · Grapes: 7
Graph 3 — Ways to Get to School (independent):
Walk: 7 · Bus: 10 · Car: 8 · Bike: 3 · Other: 2
Answer key — Graph 2: Most = Strawberry (9); Least = Banana/Mango tied (4); Strawberry got 5 more than Banana; Banana and Mango are the same.
Answer key — Graph 3: Most = Bus (10); Least = Other (2); Bus got 3 more than Car; difference between Walk and Bike = 4.
🎯 Opening Hook
Show Graph 1 (Favorite Pets). Say nothing for 30 seconds — just let students look.
"Tell me one thing you know just from looking."
Take 5 responses. Don't evaluate — just collect. Then: "You just READ a bar graph. Today we'll learn the exact words for what you just did."
🧠 Brain Break
Stand-Up Comparison!
Teacher reads two categories from Graph 3: "Walk got 7. Bus got 10."
"Stand up if you think Bus got more. Now — how many MORE? Hold up that many fingers!"
Repeat with 2 more pairs from Graph 3.
Tip: Walk around to see fingers — quick formative assessment!
🧠 ND-Friendly Tips
  • Read questions aloud — Every question on the worksheet should be read aloud before students answer independently. Never assume silent reading is accessible for all.
  • Point while asking — "Look at THIS bar" + physical point. Reduces visual scanning difficulty for students who struggle with tracking.
  • Sentence frames always available — Post the four sentence frames on the board all session. Answer structure reduces language anxiety.
  • "How many more" with fingers — Count up from the smaller to the larger number using fingers. Makes subtraction concrete and accessible.
  • Groups before independent — Graph 1 = teacher models. Graph 2 = groups. Graph 3 = independent. Gradual release reduces anxiety.
