United States of America: A Montessori Approach to Geography is a fun and interactive app that teaches young students about the different states. It is designed for younger students, but is fun and educational for all ages. The app is free to download and users are able to sample select states to learn about. There are several different activities within the app including a learning center, map by shapes and names, and a worksheet area. Purchasing the full version of the app will cost $3.99 and includes the entire map of the United States. When the app opens, the user is prompted to open the lite version of the app or purchase the full version. After going into the lite version, the user can select an activity from there. The learning center focuses on individual states and users can learn more about each state. This includes hearing the pronunciation of the state, seeing it on the map, and learning a little about the history of the state. The puzzle map by shape shows a map of the US with a state flashing. The user then has to match the state by dragging it from the area around the map and landing on the flashing state. The puzzle map by names showers users a map of the US and they have to drag and drop the state that is listed onto its matching place on the map. The worksheets section gives users fill-in-the-blank questions about the geography and history of the states. We used the app with young students who are just beginning to study geography and found it to be fun and engaging. The graphics are easy to identify and the app is fun to use. This would make an excellent addition to a Social Studies classroom. This app is recommended for users who are working on categorization and geography skills and users diagnosed with autism spectrum disorder, developmentally delayed, intellectual disorder and learning disability.
