Elevation and Distance Comparisons

This video tutorial covers the final slides of the first lesson in Unit 5 of the seventh-grade Illustrative Mathematics curriculum. It focuses on understanding sea level elevation using positive and negative numbers, with examples involving various animals. The tutorial includes exercises on comparing elevations, a mobile array, and an extension question about elevation and distance. It concludes with an exercise on ordering rational numbers.
