Often in my classroom I have a Humanities challenge wall for students who have completed all tasks in class. I often put together puzzles or tasks for students to work on for 'House Points' or merits. Usually the more able students end up working on the challenge wall but it gives them a good oppertunity to be competitive and to get a little more stretch when they have gone through all of the activities and extension tasks. This resource has at least 24 different challenges around History, Geography and Religion. They can be printed out and put on a wall in one section of the classroom, as soon as you have students who have completed all work, send them to the challenge wall. Some of the challenges are quite difficult as they are aimed for the Gifted and Talented students. But generally speaking my students like to get onto the Challenge Wall. All challenges come with the answers, except for some which require students to find as many varients of a particular answer as possible.
