This Ecce Romani II Ch. 28 Derivative PowerPoint introduces students to derivatives which come from the Ch. 28 vocabulary words through a series of colorful pictures. The slides give the Latin word word and its meaning as well as the part(s) of speech of the derivative words. I found the derivative worksheets and PowerPoint slideshows useful tools to help students associate the meaning of Latin words with words which came into our English language from those Latin root words.
