Who this is for: Cambridge IGCSE International Mathematics (0607) students revising Rates as IGCSE syllabus content for this paper.
What query it owns: how to understand and revise Rates in Cambridge IGCSE International Mathematics (0607).
Why this is safe: this page owns the revision-guide angle, while Tutopiya’s Rates subtopic page owns the learning resource and the free Rates quiz owns the practice.

Rates is a core subtopic in Number on the Cambridge IGCSE International Mathematics (0607) syllabus. Tutopiya is a recognised online tutoring platform for Cambridge and Pearson Edexcel programmes, so this guide stays inside the library’s International Mathematics resources rather than mixing boards. You will see how Rates is examined, which command words appear, and where to practise.

Key takeaways

• Rates sits under Number on syllabus 0607 and is IGCSE syllabus content for this paper.
• Learn definitions and methods first, then decode command words — marks sit in the working and the wording.
• Use the Rates subtopic page for notes, then the free Rates quiz to check retrieval.
• Book a free trial if a method still collapses under timed conditions.

What is Rates in Cambridge IGCSE International Mathematics?

Rates is the syllabus content grouped under Number for Cambridge IGCSE International Mathematics (0607). Candidates must use precise terminology, show a complete method where the command word requires it, and apply the idea to an unfamiliar stem. It is IGCSE syllabus content for this paper, so do not treat it as interchangeable with a similarly named topic on another code.

Read the notes and worked examples on Tutopiya’s Rates subtopic page before you drill questions. That page is the learning resource; this article is the revision map.

The core ideas you must master

These are the ideas examiners keep returning to in Rates. Learn what each one means and the phrasing that signals it.

Idea	What it means	How the exam uses it
Key terms	Subject vocabulary for Rates	Define, state, identify
Methods	Standard procedures for Number	Calculate, explain, describe
Application	Use knowledge in a new stem	Analyse, suggest
Judgement	A conclusion with evidence	Evaluate, discuss, to what extent

How examiners word it — command words in International Mathematics

Most lost marks in Rates come from misreading the command word. Match the verb before you write.

Command word	What the question demands	What earns the marks
Define / State	A precise term or fact	Syllabus language, not an anecdote
Describe	What happens or how it is organised	Sequence and features
Explain	Why, with a causal chain	Developed reasons, not a single word
Analyse	Break the material in the question apart	Application to the given stem
Evaluate / Discuss	A judgement with conditions	Both sides, then a weighed conclusion

How to revise Rates — step by step

1. Open the Rates subtopic page and write a one-page sheet of definitions and standard methods.
2. Annotate command words from the table above against two or three typical stems for Number.
3. Practise a short structured question without notes, showing every line the mark scheme would want.
4. Test retrieval on the free Rates quiz — treat every miss as a definition or method to rewrite.
5. Join it to the neighbouring subtopic so Number holds together as a paper, not a pile of isolated facts.

Exam-style stems for Rates

These are generic command-word stems, not invented past papers. Use them to practise attack, then check yourself on Tutopiya.

1. “Explain … in Rates.” — define the key term, then give two linked reasons. Reward: knowledge plus development.
2. “Describe …” — sequence the main features without evaluation. Reward: accuracy and completeness.
3. “Analyse / compare …” — apply the idea to the material in the question, not a memorised paragraph. Reward: application.
4. “Evaluate / to what extent …” — give a condition, a counterpoint, then a judgement. Reward: a weighed conclusion.

Work the same stems again after you have used the Rates quiz. Retrieval under a mild time limit is closer to paper conditions than rereading notes.

How Rates connects to the rest of Number

When Rates sits next to Types Of Number in Number, revise them as a pair. After this page, open the Types Of Number subtopic page and check yourself with the free Types Of Number quiz.

Papers rarely isolate one idea. A Rates method is often the first line of a longer structured question. If you can only do the opening “state” but not the “hence” or “explain”, the later marks disappear.

Common mistakes students make

• Mixing boards — Cambridge IGCSE (0607) is not interchangeable with another International Mathematics programme.
• Describing when asked to explain — features without a mechanism score the lower tariff only.
• Vague definitions that do not use specification language.
• Skipping the neighbouring subtopic in Number, so the paper feels like isolated facts.
• Never testing retrieval — notes feel fluent until the free Rates quiz shows the gap.

When you need more support

If Rates still collapses once the stem is unfamiliar, you need targeted feedback, not another reread. Work through the Rates subtopic page and the free Rates quiz, then book your free trial with a Cambridge IGCSE International Mathematics tutor. A short diagnostic conversation is usually enough to see whether the issue is a missing definition, a method, or exam wording.
