This animated power point breaks down longitude and latitude in an age-appropriate manner. It begins with hemispheres. It describes the latitude lines, then describes longitude lines. It then moves onto describe using the two together. Finally, it closes with how to plot them on a map with animated slides for practicing as a class.
This entire power point has coordinating "fill in the blank" notes. The words that are to be written by the student are in a different color throughout. I do not know how to add them to this purchase, so they are available under "Latitude and Longitude Notes" for $1.00.
