Hello, Allan teacher
Thank you for your comment on my lesson plan and I got a question.
"[w]hile writing a structure table on the board, ask students for suggestions and ask them to copy to keep their attention" instead of correctly writing, "while writing the structure table on the board, ask students for suggestions and ask them to copy in order to keep their attention". 
I just wonder when I should write just "to" or "in order to".
Thank you!
