Classroom Tools

Nine single-page classroom tools, given away and openly linkable. Each is one page that does one thing and explains itself: a fraction wall drawn so every family shares the same whole, area and perimeter, telling time to the minute, the equals sign as balance, tally and pictograph and bar graph, growing and shrinking patterns, challenge tasks for early finishers, and talk cards with a guide for the adult using them.

A teacher preparing at 8:40 in the morning needs one page that works immediately, prints on a standard black-and-white office printer, and can be used without reading anything first. Most free classroom material fails at least one of those three conditions: it needs assembly, it needs colour, or it needs a page of instructions before it can be handed out. Each failure costs preparation time at the point in the day where there is none to spend.

Teachers who need something usable within ten minutes, and parents who have been handed a topic and no context for it.

• Design of all nine tools — what each one carries, and what it deliberately leaves out
• Instructional writing, including the adult-facing guidance on each page
• Print and projection design

What the design set out to achieve. These are objectives, not results.

• One page, one idea, no assembly
• Usable projected on a board and printed in black and white, without redesign
• Explain the idea to the adult on the same page as the tool
• Give the work away openly, so it can be linked and judged directly

Each tool is a single self-contained page with everything it needs on it — nothing to unzip, no separate files to lose, nothing that breaks when the page is moved or emailed on. Each is published openly at its own address, so it can be linked from anywhere and used without an account.

Each of these follows from a published position rather than from taste. The reasoning is set out in The Learning Conditions: a child must be able to start alone, be wrong at no cost, and have an adult nearby who knows what to say next.

These are small, hand-built pages. AI’s role in them was drafting and tightening the explanatory copy, and checking the printed output behaves at page boundaries. Nothing in the tools calls a model; they are static files that work offline.

Deciding what one idea each tool should carry, and refusing the second idea. Every one of these could have been three pages. The value is that it is one, and that judgement is about what a teacher can absorb at 8:40, not about what fits.

The constraint that a tool must be complete on one page, and legible both projected on a whiteboard and printed at A4, pulls in opposite directions: projection wants large type and few elements, print wants density. The fraction wall was the hardest to hold to a single page while keeping every row on the same whole and every label readable at the back of a room.

The nine tools were built alongside the larger units and several are extracted from them, which is its own kind of iteration: an idea that needed a whole page of its own inside a unit is a candidate to stand alone. The single-whole constraint on the fraction wall is the clearest case — it is the constraint that makes the tool worth having, and it came from the misconception, not from the layout.

These are the least architecturally interesting things in this portfolio and the most immediately useful, which is worth being honest about. They are also the only artefacts here a reader can evaluate in thirty seconds without taking anything on faith. No download or usage figures are claimed; the tools are open, and that is the whole of the claim.
