The chemistry calculation builder generates calculation questions with worked solutions, laid out step by step. Five scaffold levels run from a full worked example down to blank lines for independent practice.
A hand-built replica of the real builder page, not a screenshot. Every control shown exists in the product.
Worked examples teach the method, and the support has to fade as the class gets secure, or it starts holding the stronger pupils back. The scaffold levels let you make that call in the lesson, full working for the first question, one value missing on the next, bare boxes once they are ready.
Every question is generated with clean numbers, so the arithmetic never gets in the way of the method. Choose the calculation and the subject, from moles and masses to concentrations and gas volumes, and generate a fresh one whenever the class needs another go.
Diagnostic multiple choice. Each answer reveals what the class does and doesn't understand.
Click a number and watch it land on a question at random. Built for cold-call questioning.
Automate show, cover, and recall tasks. Great for memorising diagram features or keywords.
Questions beside a visual stimulus. A YouTube clip, diagram, graph, or a paragraph to read closely.
Shell diagrams for atoms and ions, with dots or crosses, hidden electrons and side-by-side comparison.
Dot-and-cross diagrams for ionic and covalent bonding, with a stepped build-up, hidden electrons and labels.
Curated, balanced GCSE reaction equations, ready to blank for recall.
Every tool turns a few inputs into a clean, exam-ready diagram.
Practical results tables with repeat readings, a mean and an optional anomaly, plus curated reference data.
Upload any diagram and the labels are suggested for you to drag, edit and blank.
