@carly_buch are you working in the studio.code.org’s programming unit (unit 3)? If so, they have an “auto-check” feature that will check that students followed directions and will give students a “green circle” and the OK to move on. Obviously with any auto-check feature, it isn’t perfect. Some teachers check student code themselves in the teacher dashboard***. For me, I just walk around constantly and keep an eye on the students who might be motivated to try to sneak around the auto-check features. For the most part, students WANT to understand how to do the task and they can see if they got the desired result by matching their picture to the goal picture.
Does that help?
***If you have a teacher account and your students are registered in the course, you can see their work in the dashboard. If you don’t have an account, it might be helpful to make one so you can see student progress that way.
