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.

Made by rule

This kit is made in code: every time it opens, the numbers, words or arrangements are drawn fresh from its rule, so the same kit taken twice is two different quizzes from one rule. There is no answer bank to find, and the practice never runs out. Each question carries its explanation, shown at once in study mode.

The shape: big buttons

Multiple choice with buttons a small hand can hit: the same question, an interface a child can use.

Marked by rule at once, with the answer and a plain explanation shown straight away in study mode, so the child learns from the miss. A traced path is the one shape here that waits for you to grade. The parent's dashboard shows what was right, what was missed and what to try again.

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.
