![]() Before exchanging the quizzes, have students go to computers and check their answers using the interactive map and its measurement tool. They can then use their paper scales to find the answers and create a separate answer key. Have them write ten measurement questions. Have students work in pairs or independently to create a map measurement quiz using their state map. Have students create measurement quizzes. You can also click and move the cursor several times to measure a curved distance.ĥ. The tool will make a line with the distance labeled. Next, click on your starting point, such as your hometown, and then drag and double-click on another point. Select the line tool from the drawing tool bar. Project the National Geographic Mapmaker Interactive and zoom in to your state. Explain that interactive online maps have measurement capabilities that make it easy to find the distance from one place to another. Show students how to measure using the interactive map.Īsk students if they have ever used or seen an adult use a computer, smartphone, or GPS to map the route and distance to a destination. Refer students to the provided photo gallery, How to Extend a Map Scale, as needed.Ĥ. Add the length again for the third, and so on. For the second segment, double the length. Find a distance that is about half of the scale’s length, and ask students to estimate it.įor distances longer than the scale, demonstrate how you can extend the length of the scale by adding segments to your piece of paper. Sometimes it will fall between the beginning and end of the scale, and you then estimate the distance. Practice measuring distances that are shorter and longer than the scale.Įxplain that the distance between two cities will not always be the exact length of the scale. Ask: Why is the length on your paper much shorter than mine, if we are looking at the same map? (The projector makes the map much larger, so the map scale bar is larger too.)ģ. Have students do the same task with paper, pencil, and their state maps. Find two places on the map that are about the distance of the map scale you just copied and point them out to students. Explain that the measurement on the paper works anywhere on this map, but the scale will probably be different on another map. ![]() Write the number of miles (or kilometers) that this distance represents. Mark in pencil the beginning and the end of the scale. Line up a piece of plain paper so its edge is even with the map scale on the projected map. Ask: Do you see any two cities within an inch of each other?ĭemonstrate how to measure distance using the map scale. Have them use a ruler to measure the distance on the map between cities. Project the map of your state using the MapMaker 1-Page maps, and provide each student with a printed version of the map that shows the cities. Demonstrate use of the scale on your state map. Ask: Where can you find two whole cities in the space of an inch? (On a map!)Ģ.
