60 different Halloween words in the same wordsearch worksheet. You can print a big sheet stick it in the whiteboard, give colour crayons to your students and defy them to find the biggest amount of words.
Orange-o-lanterns! (No link, just wanted to remind myself of the idea). Cut the top of the orange, hollow out (be sure to not cut lining too thin or it'll melt your candy). Make faces for the oranges and fill up with goodies!
