Today's education system strongly focuses on literacy and math not social studies or science. However, as a teacher it is our job to give our students everything we have and make them well-rounded students. As a teacher, I have discovered many ways in which to make this possible from our Maxim book and in class discussion.
One of my favorite ways to learn history around the world and in the United States is through reading historical fiction. This covers literacy and social studies at the same time. Moreover, I have noticed through my own experiences that I much prefer to read a historical fiction and compare the events in the book with the actual events rather than just reading it straight from a textbook, which can be boring and dull. Books are also another great way to tie in a lesson on culture, there are numerous books out there on just about any kind of culture that students or yourself might find interesting or important. Lastly, one of the biggest ways to integrate social studies in with all the other subjects, is to simply take the opportunity to explore or answer students' questions when they ask. Too often, we easily dismiss students' questions about other subjects and move on and we talk about it later, but we either never do or do not engage the students as much as we could have when they first asked. This will be one of my goals as a teacher, to embrace the small opportunities to cover social studies whenever possible.
Lastly, one of the ideal social studies activities I would love to do with my 3rd-5th grade class would be a passport activity like the one described in the "Travel Agencies and Itineraries: A World Geography Activity" by Charles R. Beck. To me this is an idea social studies activity as literacy and math are incorporated as students discover on their own how to set up agencies and itineraries whiling researching their own information. This information or project was not given to them piece by piece, but rather the teacher gave them a broad assignment and students discovered a way to do it step by step where everyone learned, had fun, and integrated other subjects. When studying about other countries or cultures, this is an activity I will use in my classroom.
