When you want to reinforce number style questions, Ed does not limit you to simple multiple choice style questions. The Interactive Dial template asks learners to select a number by dragging a selector around a dial.
The template is special in that it has a unique interaction style - dragging in a circle, seen only in two other templates (Pie and Dial - Distribution). As such, the template is highly popular for instructional designers who like to keep their learners engaged by mixing up what the learner needs to do to progress through the lesson.
The video below will walk you through how the Dial template works and how to customize it for your educational needs.
