🔍 Grade 5 — Data Detective
Complete instructor pack for the Grade 5 data science course. Ages 10–11. Students develop critical data literacy: questioning misleading graphs, understanding probability and sampling, detecting bias, exploring data ethics, and arguing from evidence like scientists and citizens.

Classroom Supplies — Keep These on Hand All Term
Grade 5 sessions include physical simulations and research projects. Stock these once and you're set for all 8 sessions.
🧠 ND-Friendly Tips for Grade 5 (Ages 10–11)
- Post the agenda at session start — Grade 5 students navigate complexity better when they can see the whole arc. Use a visible agenda board.
- Validate intellectual difficulty — Simpson's paradox, survivorship bias, and algorithmic bias genuinely confuse adults. Say "this is hard — even professionals get fooled." It removes pressure and invites curiosity.
- Hypothesis formula card — For S2, give every student a card: "I think ___ because ___. I predict that ___." This scaffolds without limiting thinking.
- Physical simulation is essential — The S3 bead jar and S5 coin flip activities are the anchor experiences. Don't skip or digitize these — tactile engagement is irreplaceable at this age.
- Argument writing scaffolds — S6 and S7 require evidence-based writing. Use a claim/evidence/reasoning frame and post it visibly.
- Ethics discussions need ground rules — Before S7, establish "we're thinking carefully, not judging." Some students may have personal experience with privacy issues; allow passes on sharing.
- S8 capstone options — Offer: typed report option, read-from-notes presentation, and 3–5 pre-approved research questions for students who struggle to self-generate.
- Brain breaks as content — "Thumbs up/down: correlation or causation?" turns every break into a low-stakes knowledge check without written output.
