Greetings, A year ago, I reached out to Desmos HelpDesk to edit the Laser Challenge Activity which is created by Desmos. Your team has been so helpful in assisting me to make a shorter version of the activity to accept input in radian angle measure. The short version of the activity contains 5 questions only. I’m wondering if your team can assist me in duplicating this process for the original activity (which has 10 questions, 5 of which has already been edited by your team). My problem is that I have no experience working with CL. Every time I try to follow the instructions, I end up somehow getting the laser and the mirror to disappear. The only way Desmos member was able to assist me was by being added to the activity as a collaborator and doing the edits for me. Would that be possible for the longer version of this activity? I would truly appreciate any assistance as this activity aims to promote better understanding of angle measure in the context of light reflection. Here’s the link to the activity I am trying to edit so the input could be in radian: [Desmos Classroom Activities](https://teacher.desmos.com/activitybuilder/custom/6092c932b6ead304736e54d2) Here’s the activity a Desmos member helped me with editing: > **[Laser Challenge (Radian Angle Measure) • Activity Builder by Desmos](https://teacher.desmos.com/activitybuilder/custom/609222aeee7ba34d7f7cb509)** > > In this activity, students use angles to adjust lasers and mirrors as they seek to hit all three targets in a series of challenges. > > For younger students, this may serve as an excellent introduction to thinking about angle measure. For older... Regards, Hanan Alyami
