Sometimes before you teach a lesson, you'll want to preview the tasks that students will be working on. Then during a lesson, you may be asked to model a solution to a particular challenge, or to test out students' suggested solutions. All of this can be accomplished using the Preview feature.

To preview a task, click on the eyeball icon for that task. Every task in a playlist will have a preview button (see image below).

This will bring up a preview of that task in a new tab. Below is what you would see if you clicked Preview for #3 Practice Challenge.

It looks like the student view, but it does not have a navigation bar at the top. That's because task previews exist solely for the purpose of previewing or demoing a task

IMPORTANT: Any work done within the preview view will not count towards anyone's progress, and will not be saved!

Note that you can preview any task in any course (even those not assigned to your class) by navigating to the courses section, clicking on a course, and clicking on a lesson (see image below),

As you look over the lesson plan that you're teaching tomorrow, you notice that it asks you to "model solving #3 Practice Challenge for students." You open up your class dashboard. You've already assigned the lesson to your students, and you decide to try to solving #3 Practice Challenge on your own before solving it in front of the class. You click Preview for #3 Practice Challenge and start writing your code in the preview view. After a couple of minutes, you solve the challenge! You feel much more prepared for class tomorrow.

During class, after you model #3 Practice Challenge for students using the preview view, you look at your dashboard and notice that half the class is now stuck on #5 Practice Challenge. You pull the class back together and bring up the preview view for #5 Practice Challenge. "Can anyone help me solve this challenge?" Students shout out suggestions and you code them in the preview view on the smart board. After a while, you've successfully crowdsourced a solution! Students turn and talk to discuss how they might have solved it differently, and then continue working on their playlists.
