I pasted down below what CM says about Geography for you, so it can help you decide.
Geography
Just as history is the study of people in time, geography is the study of people in places. Charlotte advocated learning about people in their surroundings, not just dry facts about locations, exports, and weather descriptions. Many living books teach geography. You can also simply locate on a map or globe the geographical setting of any of the living books you read together in any subject.
In addition, Charlotte planned for a ten-minute map drill session once per week. We do map drill like this: Give each child a blank map of the region you are studying and provide a detailed and labeled map of the same region. Instruct the child to label a few areas of the region, being careful to copy the names correctly from the detailed map. The next week, give the child another blank map of the same region and instruct her to label as many areas as she can remember. Once she has labeled all that she knows, display the detailed map and check for accuracy, then have her label a few more areas carefully. Continue this routine each week, and over the course of the year she will become quite familiar with the regions studied using this gentle method.
