Give your students this Google Form (completely editable) to help you start building relationships and getting valuable insight.
 
I included some fun questions and some deeper thought questions (20 total) to get you started. Feel free to use it as is, or change it up to meet your needs. 
 
I suggest explaining the purpose of reflection to your students and how much their input means to you first, and then giving them about 5-10 mins to complete. 
 
***TO MAKE IT EDITABLE (and usable with your students), DON'T FORGET TO MAKE A COPY OF THE GOOGLE FORM***
