This activity is great teaching your students about the letter S. Who doesn't love making a sandwich?!
You can either use page one as a template to trace and cut the pieces for your students or print out a page for each student for them to cut and assemble their sandwich. Page two has labels that can be cut apart and glued to each part of the sandwich.
I punch a hole in each piece and attach them with a binder ring or piece of pipe cleaner bent into a ring.
