A maths chapter (secondary)
Secondary.

Questions with one numeric answer each and the working in the explanation, from the pages you paste: fractions, algebra, geometry, statistics, calculus, whatever the chapter holds.

What the mathematics kits are

The mathematics kits run from counting and the first number bonds through tables, fractions, percentages, algebra, geometry, statistics and calculus. The arithmetic kits are made by rule: every time one opens, the numbers are new, so a child can do the same kit every day and never see the same sum twice. The higher kits are written from your own textbook, chapter by chapter, so the questions use your course's notation and methods.

Why they are built this way

Mathematics is learned by doing many problems with feedback, and it is the one subject where a fresh problem can be made by rule without limit. A worksheet has twenty sums; a rule kit has as many as the student has minutes. The explanation after each answer shows the method, so a wrong answer becomes a worked example.

How to use them

For daily practice, open the rule kit for the child's stage and let them do ten minutes; the dashboard shows what they missed. For a course, paste the chapter and let Procto AI write from it, in the show-your-working shape where the method earns marks. Use the estimate shape for measurement and the expression shape for algebra, and set the tolerances.

Written from your material

This kit is a recipe: the shape, the number of questions, the sections and the instructions Procto AI follows. Paste your own material and the questions are written from it, each with the passage its answer came from. Procto AI is asked to keep to your material, and each key is yours to check; every question is yours to edit before anyone sees it.

The shape: estimate

A number scored by how close it is: the honest shape for measurements, estimates and anything with a tolerance.

Expressions, numbers and single-form answers are marked by rule, with tolerances and half-credit tolerances where you set them. A typed expression or chemical equation is compared sign for sign, with spacing ignored, so each form you accept is listed, and a slip that would be forgiven in a word is never forgiven here; working and code are marked by a reader against your rubric, step by step.

Taking it

Open it in study mode for the answer and the explanation after each question, and a retry of only what you missed. Switch to exam mode for the real conditions. It comes due again in a few days; the dashboard shows what is due and what you missed last time. Share it with a code for a class, print it as a paper, or host it on a screen for a room.
