Our district tests heavily on prefixes, suffixes, and affixes. I find most activites aren't geared towards the upper grades with more complex words for students in third, fourth, and fifth. I made this as a center for students to review. I simply cut out the cards after printing them on cardstock. I place them in a paper bag and have the kids pull a card. They say it to their group and they decide what the prefix is. They then fill in chart that is included. It's a great way for them to work together and see if they understand what is being taught!.
