What we've been reading

From outside, what we notice

Douglas County is among Colorado's highest-performing and most affluent districts, with a community that expects academic intensity and forward preparation. Professional respect is the currency that opens doors here — PD that doesn't treat teachers as professionals does not get a second invitation. Colorado's expanded CS standards (2024) include AI, cybersecurity, and digital citizenship strands. We design with Douglas County teachers — substantive, custom-built, materials your staff own and adapt long after the workshop ends.

Sample lessons — artifacts, not deliverables

We don't deliver lesson plans.

We deliver change for your teachers. The lessons below are the receipts.

These two examples were built for Douglas County SD — but what we'll actually do together depends on what you tell us about where you are and where you want to go. We custom-build with your teachers around what your students, your community, and your district leadership are actually navigating: AI integration, CS/STEM integration, CO policy, the local context only your educators can read. The artifacts you'll see below are one shape that capability can take.

micro:bit + AI · Precision measurement under questioning

Precision: Why Questions Matter More Than Tools

7–9 · Science / Math · 90 minutes

Kit: micro:bit + sample lesson plan — "Precision: Why Good Data and Good Questions Matter More Than Good Tools" (grades 7-9, science/math). Students design precision measurement systems with micro:bit, then evaluate whether AI improves or degrades their accuracy. Embedded AI literacy: the discipline of questioning your tools. Designed for Douglas County's culture of high expectations.

What's new — what wouldn't have happened before this PD

Without the PD, AI is the precision tool. After: students design precision measurement systems themselves, then evaluate whether AI improves or degrades their accuracy — the kind of disciplined questioning a high-expectations community recognizes as substance.

Content Objectives

  • Design a precision measurement protocol
  • Compare measurements against reference standards
  • Identify sources of measurement error

AI Literacy Objectives

  • Distinguish real precision from apparent precision in AI output
  • Apply structured verification practice to precision claims
  • Articulate when AI improves and when it degrades measurement accuracy

What Students Do

Phase 1 · 25 min Design

Teams of 3+ design a precision measurement system using micro:bit sensors. Document the protocol, expected accuracy, and known sources of error.

Facilitation focus

Don't standardize sensor placement across teams. Different microclimates make Phase 2 richer. Move between teams every 5 minutes; check that students are recording observations *and* numerical readings. The qualitative notes are the wedge they'll use to challenge AI in Phase 3.

Watch for

Teams logging only numbers. Push them to write at least one observation per reading ("breeze picked up", "cloud passed over"). If the campus has visibly varied environments — shade vs. sun, paved vs. planted — push teams to spread out.

Phase 2 · 30 min Test

Teams collect measurements and run AI analysis. Compare AI-reported precision against reference measurements; document where AI improved or degraded accuracy.

Facilitation focus

Frame the AI tool as a teammate, not an authority. When the AI prediction is wrong, students often default to "we'll fix our data." Interrupt that — the goal is to surface where AI and ground-truth diverge, not to reconcile.

Watch for

Teams that find zero divergence. Either they're smoothing data unconsciously, or the AI is generic enough to match anything. Have them pick a single 5-minute window and compare in extreme detail.

Phase 3 · 35 min Evaluate

Apply the verification protocol plus a precision audit. Class produces a list: when does AI improve measurement, and when does it introduce false precision?

Facilitation focus

The class trust guidelines are the deliverable. Push for specificity: not "AI is bad at humidity" but "AI underestimates humidity in conditions like ours when [specific local condition]." Local knowledge + data = the trust criteria.

Watch for

Generic statements ("AI is sometimes wrong"). Reject these gently — every guideline must reference a specific divergence the team observed.

A four-step verification protocol your teachers will build with us

A practice students learn once and apply to any AI output, in any subject, for the rest of their lives.

1. Check the source

Where did the AI get its data? Is it the same data we used or generated?

2. Check the reasoning

How did the AI reach its conclusion? Can we follow the logic?

3. Check against reality

Does the output match what we observed with our own senses, instruments, or knowledge?

4. Check yourself

What might we have missed? What would we want a second opinion on?

More on the thinking behind this — the framework we built it from.

Materials

  • micro:bit with high-resolution sensors (included in kit)
  • USB cables and student devices
  • AI analysis tool access
  • Precision-protocol design template
  • Reference measurement tools (rulers, scales, thermometers)

Assessment

Each team produces a one-page artifact: their findings, the AI output they evaluated, and a written verdict on when this kind of AI work is worth trusting.

Final list cites at least one case where AI improved precision and one where it introduced false precision, with reference-measurement evidence.

Teacher pack — everything you need to teach this

For the Facilitator

Prior Knowledge Required
  • Read and create simple data tables and bar/line graphs
  • Distinguish between an observation (what we measured) and an inference (what we conclude)
  • Familiarity with one-step variable assignment in block-based or text-based code
Exit Ticket

"Describe one moment today when your direct measurement told you something the AI missed. What did you measure, and what should the AI have done differently?"

Look for
  • Specific reference to a measurement (number + unit + location)
  • Specific reference to what the AI output said
  • A concrete claim about what the AI should have changed (input, comparison, caveat)
Anticipated Misconceptions

"If the AI says it, it must be right — it has access to all the data."

→ Show the AI a deliberately wrong dataset and have students predict the (wrong) output. Reinforce: AI confidence ≠ AI correctness. The AI processes whatever input it receives, including noise and bias.

"Our sensor data is wrong because it doesn't match the AI."

→ Have students re-measure with a second device or different location. Direct measurement is the ground truth — divergence with AI is a signal worth investigating, not an error to "fix."

"The AI is broken if it gives a different answer to the same question twice."

→ This is a feature, not a bug. Use it to discuss probabilistic vs. deterministic systems. Two valid outputs can describe the same data — students should learn to ask "what stayed the same?"

Differentiation
Differentiation 1 / 4
Below grade

Pre-load the data table with column headers and one example row. Pair with a peer for the AI comparison phase. Provide a sentence frame for the evaluate phase: "We trust the AI when ___ because ___. We don't trust it when ___ because ___."

At grade

Standard procedure as written.

Above grade

Add a fourth phase: students design a follow-up experiment that would resolve a specific AI-vs-observation disagreement they found. They write the protocol; they don't need to execute it in class.

Multilingual learners

Provide vocabulary cards in advance: sensor, prediction, observation, evidence, divergence. Allow team discussion in students' home language; final class artifacts can be authored bilingually. The verification protocol works in any language — emphasize that direct measurement and lived knowledge are the most authoritative inputs.

Family / Guardian Letter — copy & paste, edit to fit

Dear families, This week your student is learning a skill that will matter for the rest of their lives: how to decide when to trust an AI system. In this lesson, students used real sensors to measure conditions around our school and compared what they measured with what an AI predicted. The point is not that AI is bad — the point is that AI works best when paired with someone who knows the real situation. Your student is learning to be that someone. We call the protocol the verification protocol. It has four steps: check the source the AI used, check the reasoning, check the result against reality, and check yourself for what you might have missed. You can use this with your student at home — every time an AI assistant gives you an answer, ask: "How would we check this?"

Precision Without Tools: Estimation as a Discipline

7–9 · Math / Science · 60 minutes

Precision Without Tools: Estimation as a Discipline — Teams practice precision estimation challenges using only observation and reasoning. They compare their estimates with AI-generated predictions. Students discover that disciplined human observation often matches or exceeds algorithmic precision for local, specific questions.

What's new — what wouldn't have happened before this PD

Without the PD, estimation is a math exercise. After: students practice precision estimation with only observation and reasoning, compare with AI predictions, and discover that disciplined human observation often matches algorithmic precision for local, specific questions.

Show full lesson plan objectives · procedure · materials · assessment · teacher pack ▾

Content Objectives

  • Apply structured estimation techniques
  • Document reasoning behind an estimate
  • Compare estimation approaches and identify strengths

AI Literacy Objectives

  • Identify cases where local observation beats algorithmic estimation
  • Apply disciplined skepticism to AI precision claims
  • Articulate the value of human observation in measurement

What Students Do — No Screens, No Devices

Phase 1 · 20 min Estimate

Teams of 3+ tackle estimation challenges (how many windows in this building? how many leaves on a tree?) using only observation and reasoning. Document the estimate and the reasoning.

Facilitation focus

Print the artifact packets in color so detail is preserved. Don't tell students which AI claims are "right" — let them notice divergence on their own. Their lived knowledge of the topic IS the comparison standard. Treat it that way explicitly.

Watch for

Teams that pick a "winning" artifact immediately. Slow them down — every artifact reflects the AI's best guess given its inputs. The question is not which is right but how anyone could have known in advance.

Phase 2 · 15 min Compare

Teams compare estimates with printed AI-generated estimates for the same prompts. Identify where each approach was stronger.

Facilitation focus

Distinguish three error types: factual (X is asserted but isn't true), framing (the description emphasizes one thing while ignoring others), absence (something important is left out entirely). Most AI artifacts fail in framing and absence, not facts.

Watch for

Teams that only catch factual errors. Push deeper — what story is the AI telling? Whose perspective is implicit? What did it not have access to?

Phase 3 · 25 min Argue

Each team produces a verdict: when does disciplined human estimation outperform algorithmic precision? Connect to a community that values disciplined questioning.

Facilitation focus

Frame the argument as advice to a real decision-maker who will act on it. Students must commit to a recommendation AND name specifically what would change their mind.

Watch for

Hedging ("we can't really know"). True — but the decision still has to be made. Push students to commit to a recommendation AND explain what new information would flip it.

Materials

  • Printed estimation challenge prompts (PDF at landing page)
  • AI-generated estimates for the same prompts
  • Estimation reasoning worksheet
  • Chart paper and markers

Assessment

Each team produces a one-page artifact: their findings, the AI output they evaluated, and a written verdict on when this kind of AI work is worth trusting.

Verdict names at least one challenge where human estimation won and one where AI did, with evidence.

Teacher pack — everything you need to teach this

For the Facilitator

Prior Knowledge Required
  • Read and discuss informational text in small groups
  • Cite evidence to support a claim — written or verbal
  • Familiarity with the difference between a prediction and a confirmed result
Exit Ticket

"An AI tool gives someone you care about a recommendation. What three things should they check before they accept it?"

Look for
  • At least one item references the source or input data the AI used
  • At least one item references the AI's reasoning or comparison with known facts
  • At least one item references checking with a person, lived experience, or independent source
Anticipated Misconceptions

"AI is just like a calculator — if you give it the right numbers, you get the right answer."

→ Use a worked example where two students give the same prompt and get different outputs. AI is more like a human reader making a judgment call than a calculator computing a formula.

"If we can't see the math, we just have to trust it."

→ Pivot the protocol — "Check the reasoning" — to focus on what we CAN check: source, comparison to known facts, internal consistency. You don't need the math to evaluate a claim.

"AI hallucinations only happen with chatbots."

→ Show a printed AI example that contains a confident but factually wrong statement. Hallucinations are a property of how generative models work, not a chatbot quirk.

Differentiation

Reduce to two artifacts in the packet (instead of three or four). Provide a graphic organizer with three columns: What the AI said / What I know / What I would tell someone who asked me. Sentence frames provided for the final argument.

At grade

Standard procedure as written.

Above grade

Add a meta-question: students draft two or three rules for when the kind of AI tool in this lesson should and should not be used by adults in their lives. The rules are evidence-cited from the packet.

Multilingual learners

Encourage discussion in students' home language. The artifacts in the packet can be discussed in any language — the analysis transfers. Final class artifacts can be authored bilingually. Pair vocabulary cards if helpful: source, reasoning, reality, evidence.

Dear families, This week your student practiced something most adults haven't been formally taught: how to evaluate an AI-generated claim before accepting it. In this lesson, students worked from printed artifacts — no screens — and applied a four-part verification protocol: check the source, check the reasoning, check the result against reality, and check yourself. They learned that the right answer to "should I trust this AI?" is almost always "let me check first." At home, you can use the same protocol. The next time an AI assistant gives your family information, ask your student: "What would we need to check before we acted on this?"
