PDF Lesson 6 Level 7-8 B 2D Geometry-class student

Pdf Summary

The document outlines a Math Kangaroo course for Level 7-8 students focused on 2D Geometry. It includes a structured curriculum comprising lessons that integrate calculations with rational numbers, number theory, algebraic thinking, and geometry—both 2D and 3D—circles, statistics, combinations, and logical thinking.<br /><br />Key concepts introduced in 2D geometry include the properties of lines, segments, and angles, with an emphasis on understanding the geometry of triangles and polygons. Students would use knowledge about congruent and similar figures, angle bisectors, perimeter, and area calculations, applying formulas like those for circles, rectangles, and triangles.<br /><br />The course employs a 4-step problem-solving strategy: understanding problems, planning solutions, executing the plans, and reflecting on the correctness of solutions. This process can be applied to various exercises, addressing questions typical of Math Kangaroo contests, such as finding intersection points of diagonals in shapes or understanding properties of parallel and perpendicular lines.<br /><br />Students are familiarized with essential geometry vocabulary, such as congruent, similar, and bisectors, and they learn to solve problems involving these concepts. The program includes diverse sample problems from past Math Kangaroo contests to challenge students, ranging from calculating differences in perimeters to determining area ratios in composite shapes.<br /><br />Additionally, the document mentions a “Genius Hour” project, enabling students to apply learned skills to create a presentation with problem-solving demonstrations. The course concludes with strategies to solve geometry problems, encouraging practice using contest problems and solutions available on the Math Kangaroo website.<br /><br />Overall, the course aims to strengthen problem-solving skills and enhance understanding of 2D geometry through interactive and applied learning experiences.
