This is a slide show with pictures of real-life grammar fails. It was originally used around Christmas time, which is why there's several pictures related to Christmas on it, but can be used anytime of the year. My students LOVED this activity. We first reviewed some grammar rules and mistakes in our own writing before turning this into a competitive activity, which is totally optional. I had my students compete for finding the most mistakes for a piece of candy at the end. Hope you enjoy it!
