This document presents the problem set for the 31st International Kangaroo Mathematics Contest (IKMC) held in 2021, specifically tailored for the PreEcolier category (Class 1 & 2). The IKMC is a globally recognized competition designed to stimulate young minds and cultivate a foundational interest in mathematics. It emphasizes creative problem-solving and logical reasoning over rote memorization. Understanding the types of questions posed in this contest is crucial for students, parents, and educators aiming to prepare for similar challenges. This paper serves as an invaluable resource to familiarize participants with the contest format, problem complexity, and the fundamental mathematical concepts targeted at this early educational stage, thereby fostering analytical thinking from a young age.

Nội dung tóm tắt
The 31st International Kangaroo Mathematics Contest 2021 for PreEcolier (Class 1 & 2) features a diverse collection of problems aimed at assessing fundamental mathematical understanding and cognitive skills. The contest is structured into sections with varying point values, gradually increasing in complexity from 3-point to 5-point problems. Questions encompass areas such as spatial reasoning (e.g., constructing shapes from sticks, mirror images, identifying overlapping patterns), basic arithmetic and number sense (e.g., sum of stars, counting, comparing heights, understanding numerical sequences), and logical deduction in various contexts (e.g., toy shelf arrangements, pathfinding, deciphering codes, comparative analysis of quantities). Many problems are presented with engaging, child-friendly scenarios involving animals or everyday objects, making abstract mathematical concepts more accessible. The methodology employed by students typically involves visual analysis, trial and error, simple calculation, and systematic reasoning to select the correct multiple-choice answer. Beyond mere calculation, these problems encourage students to think critically, analyze situations, and apply basic principles creatively. The value of this paper extends to providing an excellent practice ground, allowing young learners to develop essential problem-solving strategies, enhance their quantitative aptitude, and build confidence in their mathematical abilities. It also offers insights for educators and curriculum developers into effective ways of teaching and assessing early mathematical concepts, ultimately fostering a strong foundation for future academic success in STEM fields.
