This resource focuses on the foundations of 2D mapping through the exploration of city grids. Students will learn to identify horizontal and vertical number lines as crucial elements for navigation and future coordinate mapping. They will engage with a scenario where they plan a new city, identifying key locations such as Town Square, Main Street, and Central Avenue, which intersect to form a grid layout. The document encourages visual analysis of the grid and tasks students with drafting their own city map, reinforcing their understanding of spatial relationships and grid foundations.
