Print out a sheet with 36 small boxes arranged in a grid. On half the boxes, write the names of prefixes and on the other half write their meanings. Student will cut out the boxes and arrange them in a square with the prefixes and their meanings face down. In pairs, students will flip two squares at a time, trying to match the prefixes with their meanings. The student with the most pairs at the end is the winner.
Hand out a sheet with 15 or more illustrations or objects. Beforehand, write out a number of suffixes on slips of paper and put them in a container. Pass the container around to students and have them pick three slips. Students should use their suffixes to transform the ideas in the pictures into as many words as they can create. For example, if a student had the suffix "ness" and there was a picture of a happy face, they could turn this into "happiness."
Divide students into two different teams and have them stand in lines on opposite sides of the room. Each team will send one person at a time to the board and you will give them a prefix. The players will then try to write as many words as they can think of in 30 seconds using the prefix. The team with the most words gets one point. Both players can get an extra point for their team by explaining what all the words in their lists have in common. The team with the most points wins.
Find words with 15 different suffixes and write them on a 3-by-5 index card. Cut the words in half between the stem and the suffix. Hand out stems to half of the class and suffixes to the other, and have them search for the person who has the corresponding stem or suffix. Tell students to look up and copy the meaning of their word from the dictionary, including the meaning of the suffix, when they find their partner. When everyone is finished, have each pair share their word and definition.
