For a recent Halloween lesson I did a series of 6 games, and one of them was putting together a puzzle to find the hidden Halloween message. (My third years also enjoyed this because it was a fun culture/game lesson for Halloween so it might be a nice addition to something else like this!)

I found out though that my special needs students get really really into puzzles! Even the more energetic ones were focused on figuring out the message.

Because it was a Halloween lesson, I found images relevant to Halloween, and either made sure/added myself, a Halloween message like "Trick or Treat!" or "Happy Halloween!". I laminated and cut up the picture, making a puzzle! I have 7 students in my class so I made two puzzles, and separated the groups based on what students get along. My students this year, aside from one or two, are low level, so this was a good amount of English for them. They can read it and write it down on their worksheet/in their notebook.

Lately my special needs students have been really into Undertale, so I made a puzzle out of that and they were so happy with it!! So asking about what kinds of characters and games they like before you make something might be nice! ^_^

I think this can be best used as part of a culture lesson! It doesn't have much English involved besides some reading and maybe writing or speaking, but in a lower level class, or classes where talking in pairs or a group is difficult because of the class dynamic, it's a good way to sneak in some English while doing a lesson that is intended to be more game-based.
