Keep things relatable to students. Also be creative, while cellphones should be put away, to limit distractions for students, you can use social media templates to fill the void of cell phone usage. This template I use for "Do Nows" or drills. Each phone represents a day/a single drill. You can add lines in them for students to write on. My thought process behind this template, is snapchat is quick like "ahh ha" moments you want to capture or share. Hence, a drill you are either revisiting a topics from the class before or you are thinning of ahead for the topic that day. Either way, a drill is usually brief that swegways into the lesson for that day.
