PDF Lesson 7- Level 5-6 - 2D Geometry- Presentation

Pdf Summary

The document is an outline of Math Kangaroo geometry problems for Levels 5-6, focusing on 2D geometry. It lists various math problems from past Math Kangaroo competitions, providing a glimpse into the typical questions asked.<br /><br />The repeated problem "(MK 1999 #5)" asks how many times faster the minute hand of a clock moves compared to the hour hand, a basic question intended to focus on understanding time movement in clock-related mathematics.<br /><br />Other problems include:<br />- Constructing a square and calculating the area of a smaller square formed by joining midpoints (MK 2016 #5).<br />- Determining which part of a square is colored (MK 2021 #10).<br />- Comparing the fence length of different rectangular plots of land to determine who has the longest (MK 2000 #15).<br />- Counting the number of convex angles formed by rays at a vertex (MK 2002 #16).<br />- Determining the width of wooden pieces used to frame a painting, based on perimeter measurements (MK 2005 #19).<br />- Calculating the total area of a rectangle divided into smaller squares with side lengths provided (MK 2010 #24).<br />- A bonus question about finding the area of a shaded figure composed of isosceles right triangles (MK 2003 #28).<br /><br />Each problem is centered on key geometry concepts like area, perimeter, shape transformations, and angle measurements. The document suggests that drawing and diagrammatic representation are valuable aids in solving these geometry problems. Optional homework includes reviewing the Math Kangaroo exam from 2019. The wrap-up emphasizes the variety of flat shapes encountered in these problems, typically requiring calculations of area or perimeter.
