Rather than create a worksheet and use a lot of paper, doing a blackboard survey puts all the information up on the board for all students to see and review once the communication part of the activity is over.
This activity works well with most walk-and-talk information collecting communication activities. Also, it's a no-prep activity so you can use it any time.
This fun Halloween activity idea for elementary English classes isn't so much about studying and practicing English as it is about sharing culture and just having a fun lesson. When planning a lesson, I'd save this for the end as a "reward" for completing the earlier part of the lesson.
