# reSolve: Location: My Place in Space

This series of two lessons explores locating points and calculating distances using the Cartesian plane. In the first lesson, students locate and describe points on the Cartesian plane using ordered pairs of coordinates. They then search for squares on a given plane and find the side lengths of the squares. In the second lesson, students find the vertical and horizontal distances between points on a Cartesian plane and use this to solve a problem of finding the best location for a depot for an ice-cream delivery business. The sequence is outlined in detail including curriculum links, vocabulary, materials needed, presentation slides, discussion points and student resources. This sequence is part of the reSolve: Mathematics by Inquiry program.
