Assembly Work Tasks: Workbasket Wednesday LinkUp
I love these flashlights from the dollar store. Each flashlight (sometimes 2) are $1. However, once you have them, you can use them as a task right out of the box. Students can assemble or disassemble. It could just be the batteries or the light mechanism as well. From Autism Classroom Resources Workbasket Wednesday.
