Pdf Summary

The Math Kangaroo 2018 competition for Levels 7 and 8, held on March 15, 2018, featured 30 mathematics problems for participants to solve within a 75-minute limit. Calculators were prohibited, and participants needed to submit their answers on a designated form with their names and ID numbers provided. The questions were organized into three tiers of difficulty, each offering a different number of points: 3-point, 4-point, and 5-point problems.<br /><br />The 3-point problems (1-10) included questions on basic arithmetic operations, symmetry in words, geometry involving triangles and rectangles, and practical problem-solving skills, such as calculating required steps or route variations. The focus was on straightforward calculations and logical deductions.<br /><br />The 4-point problems (11-20) were slightly more complex, adding layers of arithmetic operations with conditions, spatial reasoning, and logic-based questions. Challenges included estimation, puzzle-like situations with hidden information, and more intricate geometric reasoning.<br /><br />The 5-point problems (21-30) required deeper analytical thinking and problem-solving skills. These included election vote calculations, spatial reasoning involving volumetric calculations, and geometry problems such as calculating angles or areas of complex shapes. Participants also needed to solve problems related to speed, comparisons among expenditures, and algebraic operations leading to uncovered values.<br /><br />Overall, the contest emphasized a variety of mathematical disciplines including arithmetic, geometry, and logic to challenge participants' understanding and problem-solving capabilities. Each question was designed to test not only mathematical knowledge but also the application of mathematical thinking in novel contexts.
