For teachers

Presentation decks

6 standalone teaching decks, one per section. Each is a single HTML file with the slides, the videos, the interactive tools, the check questions and the speaker notes already inside it — email it, put it on a USB stick, or open it straight from a projector laptop. Nothing to install.

36 slides 24 embedded videos 27 interactive tools 69 quick checks Dark or light theme

How the decks work

Reveal in stepsPress or Space and the bullet points appear one at a time, then the worked example. Nothing is on screen before you want it there.
Video built inThe lesson video that matches each slide sits in the side panel — no switching tabs mid-lesson. (This is the only part that needs the internet.)
Interactive toolA live model for the idea on that slide: a jumping number line, a sign-rule table, a 100-grid that highlights multiples, a factor comparer, a divisibility checker that explains every test, a powers explorer and a square-root estimator.
Quick checksOne or two questions per slide, drawn from the same verified bank as the practice pages. Type an answer and it marks instantly, or press Reveal for the full method.
Speaker notesPress N. Each slide has notes on what to model, the misconception to watch for, and a suggested time.
Discussion promptEvery slide has a question to put to the class, in the Discuss tab.
Presenter controlsO overview · T lesson timer · D dark/light · F full screen · 19 jump · ? shortcuts. Works with a presenter remote.
