Session 7 — Our Second Survey

Instructor Cheatsheet · Data Science for Young Minds · Grade 2 · Ages 7–8
~50 min Ages 7–8 Session 7 of 8 ND-Friendly Student-Designed Survey
Session Goal

Students design and run their own class survey. They choose a good data question, make a recording sheet, survey 8 classmates, and build a tally chart from their results — applying every skill from Sessions 1–6.

Agenda
TimeActivity
0–5Hook: "What would YOU want to ask?" quick share
5–12Review: what makes a good question? Sentence starters card
12–22Question Planning: students draft + teacher checks fairness
22–35Survey Time: survey 8 classmates, record on sheet
35–43Build Tally Chart from recording sheet
43–47Brain Break: act out most popular answer
47–50Share out + Wrap-Up
Vocabulary to Reinforce
  • Design — plan something on purpose
  • Investigate — look closely to find an answer
  • Question — what we want to find out
  • Sample — the group we ask (not everyone)
  • Results — what we found out
Post these on the board. Students don't need to memorize — just recognize and use them.

Question Starters Card — Print 1 per Student or Post on Board

"What is your favorite ___?"
"How many ___ do you have?"
"Which do you like more: ___ or ___?"
"Do you prefer ___ or ___?"
"What color is your ___?"
"How often do you ___?"
Answer choices should be 3–4 options and cover all possibilities (add "Other" if needed).

Fairness Check — Review Each Student's Question

Can it be answered with one of the choices?
Does everyone understand what it means?
Are there 3–4 clear answer choices?
Is it kind — not about looks or personal things?
Would you feel comfortable answering it yourself?
If a question fails any check, say: "Great idea! Let's make it even better. Can you change ___?"

Suggested Survey Script (give to students)

Step 1 — "Hi! Can I ask you a question for our class data?"
Step 2 — Ask your question out loud: "My question is: ___?"
Step 3 — Show your answer choices: "Your choices are: ___, ___, or ___."
Step 4 — Wait for the answer, then mark a tally next to it.
Step 5 — "Thank you!" — move to the next person.
Survey Setup Tips
  • Model the whole survey process before students begin
  • Set a visible timer for 10–12 minutes of survey time
  • Assign a "home base" so students aren't chasing each other
  • Remind students: survey 8 people (a sample, not everyone)
  • If stuck, reduce to 5 people — results still valid for practice
  • Circulate to help students mark tallies correctly
Brain Break (min 43)

Act Out the Winner

  • Each student shares their most popular answer
  • The class acts out or mimes that answer
  • E.g., "My most popular was swimming" → everyone pretends to swim
  • Fast-paced: 10 seconds per student, keep it moving

ND-Friendly Instructor Notes

  • Question starters card on every desk — reduces blank-page anxiety; students can point to a starter instead of generating from scratch.
  • Fewer people is okay — surveying 5 instead of 8 still produces real data. Never make a student feel behind for a smaller sample.
  • Pre-approved question bank — have 4–5 pre-made questions ready for students who struggle to design their own. Let them choose one and add their own answer choices.
  • Non-verbal survey option — student shows a card with their question + choices; classmate points to their answer. Mark the tally for them.
  • Visual timer on board — reduces anxiety about "how long do I have?" during the survey activity.
  • Fairness check is collaborative — frame it as "making your question even better," not as correction or rejection.
  • Tally chart template pre-drawn — on the worksheet, the chart header and column labels are already set up; student fills in their own question + choices + tallies.
