TrussCraft

Build a bridge. Run the load test. Watch the forces.

A bridge-building game for teaching statics. Students lay roadway, timber, steel and cable across a gorge, then send a truck over while every member lights up blue in tension or red in compression. Each of the seven levels forbids the last level's answer, and every budget was set by searching for the cheapest bridge that actually survives.

• Seven levels, from triangulation to cantilevers
• Live Verlet physics with Euler buckling
• Every failure explains which member gave way, and why
• One offline HTML file: no install, no libraries

• Vanilla JS
• Canvas
• Web Audio
• Verlet physics

Like Terms Match

A neon match-three where only like terms combine.

Swap tiles on a rotating 3D board to line up three or more like terms and simplify them. Coefficients don't matter, only the pronumeral and its power, which is the whole lesson. PEMDAS bombs clear rows and columns, divide-by-zero traps cost you shields, and the colour-coding fades away as students level up.

• 3D board you can spin mid-game
• PEMDAS bombs and divide-by-zero traps
• Scaffolding that fades as students improve
• Arcade high-score table, initials and all

• Three.js
• WebGL
• Single HTML file

Plate IVAI writing coachAll HSC subjects

Band 6

An AI marker that grades like a senior HSC examiner, then shows you the next band.

Students answer an HSC question and get it marked against the NESA band descriptors by a deliberately ruthless marker. A response that describes when the question says analyse is capped at Band 3, however long it is, and every mark comes with specific Band N+1 feedback. Teachers get a syllabus navigator, a question generator and an audit that fills gaps across a whole course.

• Marks against NESA band descriptors and command verbs
• Specific Band N+1 feedback on every response
• Syllabus navigator down to individual dot points
• Offline-first, with classes, quotas and a choice of AI providers

• React 19
