Earlier this week, a reader of my weekly newsletter sent me an email asking for advice on how to view a document and a countdown timer on the same screen. The idea is that the document is displayed on a large screen via an LCD projector or Chromecast and a small timer is also displayed. The document could show questions that students can answer, or procedural steps that they must follow over a set period of time.
I offered a simple suggestion for viewing the document and a timer on the same screen. My suggestion was just to resize two browser tabs so that the entire document and a small timer are displayed on the same screen space. This short video shows how to do it.
