Unified International Mathematics Olympiad (UIMO) Class 6: syllabus, dates and exam pattern (2026–27)

Two things about this paper are worth more than the chapter list. First, Mathematics-2 is not a harder version of Mathematics-1 — it is a different question type. Five questions, numbered 31 to 35, have more than one correct option (two, three or four of them can be right), and a child has to darken every correct one on the OMR sheet to earn the 3 marks. That format barely appears in school tests, and it is 15 of the 60 marks. Second, five topics that Class 6 olympiad papers still draw on are not in the 2026-27 Ganita Prakash book at all: Roman numerals, ratio and proportion with the unitary method, the introduction to algebraic expressions, simple one-variable equations, and the recognition of 3-D solids and their faces, edges and vertices. All five sat in the previous Class 6 NCERT, and they went to four different places. Ratio and proportion with the unitary method is the one our curator taxonomy carries as a Class 6 olympiad-scope topic beyond the book, and our Class 6 maths practice keeps it in scope. Algebraic expressions and simple one-variable equations moved up one year and are Class 7 chapters now — Expressions using Letter-Numbers, and Finding the Unknown. The recognition of 3-D solids with their faces, edges and vertices moved up two, into Class 8's Exploring Some Geometric Themes. Roman numerals are the only one with no home in the Classes 6 to 8 spine at all; the nearest thing to them is Class 8's A Story of Numbers, which is about numeral systems in general. So four of the five are still worth practising for this paper, but a parent should know they will not find four of them in this year's book. Separately, Logical Reasoning (10 marks) and Critical Thinking (5 marks) are their own spine — a quarter of the paper that no maths chapter feeds.
