Year 3 computing: the foundations year

How to read the per-year pages: year labels are bands, not prescriptions — children progress by mastery, and a class's real spread spans years in both directions (the differentiation page). These pages describe what's developmentally sensible to be working on in each band, with the reasoning cited, so teachers and parents can calibrate — not audit.

Year 3 (around ages 8–9) is computing's foundations year for a precise reason: it sits inside the readiness window — fine-motor control and letter knowledge are in place, while self-taught bad habits haven't yet compiled. What's built now is built once; what's skipped now gets retrained later at the retraining price.

The year's work

Machine operation: mouse fluency (click, double-click, right-click, drag — taught, not assumed), knowing the machine's parts, and the operator identity — you run this thing, it doesn't run you.

Typing, begun properly: formal home-row instruction starts this year — short, frequent, accuracy-first sessions; speed targets wait for technique. This is the single highest-stakes timing decision in primary computing.

First files: the filesystem mental model — things live in places, folders nest, names matter — built concretely before app-centric habits bypass it.

First spells: copy, paste, undo — the earliest shortcut vocabulary, learned as chords from the start (children this age meet chords as magic, not retraining).

Safety foundations: secrets stay secret (passwords, personal information), kindness applies online, and tell an adult installed as competence — the year's safety work is dispositional, not procedural.

First programming: sequencing — precise instructions to a literal executor, the ladder's first rung — and the discovery that the machine does exactly what you said, which is the concept everything later stands on.

What to hold back

Multi-app projects, spreadsheets, and open web search sit better later — this year's job is fluencies, and an hour a week spent on foundations pays compound interest that skipping ahead forfeits. Search, if touched, stays inside curated collections.

The checkpoint questions

By the band's end, on performance not quizzes: can they steer the mouse precisely and right-click on purpose? Type short text with correct fingers (slowly is fine — correctly)? Save something and find it again? Copy and paste with keys? Say what they'd do about a mean message or a stranger's question? Sequence a simple program and predict what it does?

How Wiz Kids maps

The early realms are this page: Meet the Machine, Typing Temple's home-row arc, File Forest's first levels, First Spells, Wizard Safety's foundations, and the Charm Forge's sequencing lessons — with placement meeting the children who arrive ahead or behind the band, which is most of them.
