Enjoy this freebie! I have used this as a supplemental item to allow students to compare past and present pictures of an elementary school. Feel free to change or add to it to fit what you are looking to address. Gallery walks are a great way to get students moving and collaborating around the classroom and allow them to compare and contrast. :) This particular graphic organizer was geared for 1st graders, but it could be tailored to fit the needs of many students!
