IMO Class 2

The SOF International Mathematics Olympiad (IMO) for Class 2. Olympiad mathematics is not harder school mathematics. Most questions are solvable with the syllabus a child already has; the difficulty is noticing which piece of it applies to a problem they have not seen before.

At this age the paper is read to a child as much as by them. The value is not the rank; it is twenty minutes of sustained attention on problems that do not look like homework.

The paper

35 questions in one hour, for 40 marks.

Section	Questions	Marks each	Total
Logical Reasoning	10	1	10
Mathematical Reasoning	10	1	10
Everyday Mathematics	10	1	10
Achievers Section	5	2	10
Total	35		40

The Achievers Section is 5 questions at 2 marks each — 10 of the 40 marks from a tenth of the questions. It is where the paper is actually decided, and it is the part most preparation skips.

What is on the syllabus

Logical Reasoning

Patterns, Odd One Out, Measuring Units, Geometrical Shapes, Analogy, Ranking Test, Grouping of Figures, Embedded Figures, Coding-Decoding.

Mathematical Reasoning

Numerals, Number Names, Number Sense (3-digit numbers), Computation Operations, Length, Weight, Capacity, Time, Temperature, Money, Lines, Shapes and Solids, Pictographs, Patterns.

Everyday Mathematics and the Achievers Section draw on the same syllabus as Mathematical Reasoning above — set in context, and at higher order.

How Sophoz prepares for it

Practice is weighted towards problems whose shape is unfamiliar, because that is the skill the paper tests. Hints open up an approach rather than giving away the step, so the child still does the noticing.

Sessions are paced backwards from the exam date, with earlier topics revisited at widening intervals. Spacing beats massing by a wide margin — it is the best-evidenced result in learning science.

Mastery is tracked per skill rather than per subject, so a weak area is visible instead of being averaged away inside a percentage.

Before you register

Registration is through the school; SOF does not generally accept individual entries.
