Students are challenged to complete the rebus puzzles and brainteasers based on prior knowledge of WWI vocabulary. Features key people, places and battles. I used this within my class as a hook to a lesson or a ABC (activity before content). This is a creative way for a review and forces students to think critically. My students enjoyed me "mixing it up" on them and, hopefully, your student will have just as much fun! There are 4 task cards that have been left empty for you to add your own. Answer key is provided.
