Tired of the same old bell-ringers? Then, I have the solution for you! This 23 slide powerpoint provides 12 visual mind puzzles for your students to solve. I use them as a warm-up from time to time and my students love them! These logic problems are perfect for engaging students and forcing them to actually put forth effort to solve a problem. Most of the slides have an answer slide diagramming the solution. Look at the preview for more details!
