The document describes a memory exercise called Kim's Game using pictures. The exercise involves presenting students with slides containing a set number of pictures, starting with 4 and increasing to 7. Students must memorize the pictures and then identify which one is missing from a subsequent slide where the positions have changed. The time limits for memorizing and responding can be adjusted. Strategies like verbal rehearsal and visualization are suggested to help students who struggle. The background color can also be customized for each student.
