When creating a TeacherMade activity, you are working within the Activity Editor. This view is only visible to the Teacher and is for creation purposes only. 

As you add different item types and set the correct answers, you will be able to see those answers on the page. For example, if you add a Short Answer item type to the page, the correct answer will be visible to you within the answer box. The same goes for our Math Number tools. Matching questions will be matched, Multiple Choice will be selected, etc. 

Again, the Editor is strictly a Teacher's view. If you want to see what your students will see, use the Preview tool.
