Cartesian Grid Distance - Intro

Unit 44

This math unit begins with understanding the basics of Cartesian grids, such as calculating straight-line distances and understanding directions between points using simple movements like right, left, up, and down. Students then progress to applying geometric concepts such as the Pythagorean Theorem to calculate the lengths of sides in right triangles, focusing initially on identifying and using labeled sides in equations, and gradually moving towards expressing these lengths as radicals and decimals. As the unit advances, the complexity increases, integrating skills to calculate distances and directions on Cartesian grids using angles, and interpreting these distances both numerically and as radicals. The practice evolves from straightforward distance calculation between two points directly along grid lines to determining distances and directions expressed as vectors and angles, further utilizing the Pythagorean Theorem implicitly to compute distances shown as square roots. Towards the end, students apply the distance formula extensively, calculating the distances as radicals and understanding deeper spatial relationships in two-dimensional space through various problems that contextualize theoretical coordinate geometry into practical scenarios. Overall, the unit builds from foundational grid navigation and basic geometric calculations to sophisticated applications of algebra in geometry, enhancing both spatial awareness and algebraic skills.Skills you will learn include:

  • Pythagorean theorem
  • Distance on the cartesian grid
  • Distance based on coordinates
