I have a student who will NOT work with me for anything. I literally offered him a sticker once and he fled the room. However, his FAVORITE thing in the world is the children's horror game "Five Nights at Freddy's". When I showed him that these photos from Five Nights at Freddy's were what we'd be working on, not only did he say the words for me with no issues, but he asked if he could do some more!
Anyways, if you have a student who is SUPER into that game, I really do recommend this! I turned it all into a folder game, by putting the backdrop from Five Nights at Freddy's on the folder, then cutting out and laminating each photo. Then my student could put the characters on as he wanted in different scenes every time he said the word or identified the plural/singular.
