What we've been reading

From outside, what we notice

Prince George's County is the 18th-largest district in the U.S., serving a community shaped by the federal government, Howard University, and the military corridor — under Superintendent House's leadership with explicit equity focus. The implication for PD is structural: the work has to land at every school, not just the well-resourced ones. Maryland's CS-for-all and SB 980's AI and cybersecurity additions create the policy expectation. We co-design with PGCPS — custom-built to reach every school, not just the well-resourced ones, with materials and practices that continue past the workshop.

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 Prince George's County PS — 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, MD policy, the local context only your educators can read. The artifacts you'll see below are one shape that capability can take.

Every School, Every Student: AI and Equity

6–8 · Science / Social Studies · 90 minutes

Kit: micro:bit + sample lesson plan — "Every School, Every Student: How AI Can Support (or Undermine) Equity" (grades 6-8, science/social studies). Students examine how AI tools perform differently in different school contexts — and what that means for equitable access. Embedded AI literacy: AI equity evaluated through direct student experience.

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

Without the PD, AI works the same regardless of school. After: students examine how AI tools perform differently in different school contexts — and produce evidence of where AI supports equity and where it undermines it. Equity work, classroom-level.

Content Objectives

  • Pair measured data with school context
  • Compare AI behavior across school contexts
  • Construct evidence about equity-relevant AI behavior

AI Literacy Objectives

  • Identify equity implications of AI behavior across contexts
  • Apply structured verification practice to equity-relevant AI claims
  • Articulate when AI supports versus undermines equity

What Students Do

Phase 1 · 25 min Collect

Teams of 3+ collect environmental data on campus and pair it with a school-context card describing a different school in the district.

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 Compare

Teams query an AI tool to analyze their data and provide recommendations. Compare AI behavior across the team's context and the contrast school context.

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 an equity audit. Class produces evidence about where AI supports and where it undermines equitable access — relevant to PGCPS's mission.

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 sensors (included in kit)
  • USB cables and student devices
  • AI analysis tool access
  • School-context cards (different demographics, resource levels)
  • Equity-comparison worksheet

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.

Evidence cites at least one specific AI behavior difference between contexts and the equity implication.

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

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?"

Every School Deserves This: The Equity Audit

6–8 · Social Studies / Math · 60 minutes

Every School Deserves This: The Equity Audit — Teams examine how a fictional AI resource-allocation system distributes materials across schools with different demographics. They identify bias and propose corrections. Connected to PG County's equity mission.

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

Without the PD, an AI resource-allocation system is a black box. After: students examine how a fictional system distributes materials across schools with different demographics, identify the bias, and propose corrections — exactly the equity audit PGCPS's mission demands.

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

Content Objectives

  • Read system output for distributional patterns
  • Apply equity criteria to algorithmic decisions
  • Construct corrective recommendations

AI Literacy Objectives

  • Identify equity bias in algorithmic resource allocation
  • Apply audit standards to AI systems
  • Articulate corrective interventions

What Students Do — No Screens, No Devices

Phase 1 · 20 min Examine

Teams of 3+ examine the printed AI system's output for resource allocation across schools with different demographics. Document the patterns.

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 Audit

Teams apply equity criteria from the audit worksheet. Identify bias patterns and propose specific corrections.

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 an audit report with documented bias and proposed corrections. Connected directly to PGCPS's equity mission.

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 AI resource-allocation system output (PDF at landing page)
  • School demographic data cards
  • Audit worksheet with equity criteria
  • 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.

Audit report cites at least two specific bias patterns and proposes a concrete correction for each.

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.

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?"
