This document provides instructions for using Google Maps in the classroom. It explains that teachers can create custom maps and share them with students through links or by embedding maps in webpages. Maps can be used across subjects to estimate distances, convert measurements, and calculate ratios. Google Maps allows users to add place marks, lines, shapes, descriptions, photos, videos and links to maps. The document then provides step-by-step instructions for navigating to Google Maps, using the My Maps feature to save and annotate custom maps, collaborating on maps, and adding various annotations to maps.
