Step 1: Brainstorm - Ask students to brainstorm some prefixes.
Question: We’ve already learned about prefix. Can you give us some examples？
Possible Answers: “re-”, “un-”
Step 2: Board Race - Divide students into three two groups. Ask students to think of examples with prefix “un-” and “re-” and write them down on your worksheet. Have students come front one by one to write down words with the prefixes “un-” and “re-” on the blackboard. The group comes up with most words wins the game.
Possible Answers: unhappy, unhealthy, unclear, untrue, unusual, uncomfortable, unbelievable,unkind, retell, rewrite, review, repeat, recycle, return
Step 3: Encourage students to think about the meanings of “un-” and “re-”.
Possible Answers: “un-” means “not”, “re-” means “again”
Teacher’s Brief Summary: A prefix is a group of letters added before a root word to change its meaning and create a new word so it is essential for us to know about the meaning of prefixes.
Step 4: Show students some new words with prefixes “un-” and “re-” and let them guess their meanings.
Possible Answers: “unexpected” means “not expecting it”; “unaware” means “not aware of something”; “unfold” means “flat something that has previously been folded”, “uncover” means “remove something that is covering it” ; “renew” means “start something again”; “remove” means “take something away from one place”; “replace” means “remove somebody or something and put another person or thing in their place”; “restore” means “bring something back again to a former situation”

Step 1: Present two pictures, ask students to figure out the meanings of the prefixes “il-” and “ir-”.
Possible Answers: “il-” and “ir-” means “not”
Step 2: Present two sentences and ask students to figure out the meaning of the prefix “trans-”.
Possible Answers: “trans-” means “change”
Step 3: Encourage students to form new words by adding proper prefixes.

Step 5: Ten Strikes and You’re Out– Ask students to guess the word according to the definition. Every time if they guess a letter incorrectly, they lose one point. Ask them to guess all of the missing letters before they strike out.
Step 6: Present three words students are familiar with, ask them to figure out the meaning of “en-” and make them add words to complete sentences.
3. Using prefixes (Ludo Board Game)
Step 1: Divide students into groups, each of which consists of 4 players. Each player chooses one of the 4 colours (green, yellow, red or blue) and places the one piece of that colour in the corresponding starting space.
Step 2: Players roll the dice and give a word which starts with the prefix on the dice. If a player fails to give an example or repeat the words other players come up with, he couldn’t move his piece. Players take turns in a clockwise order.
Object: The first person moves his piece to the home space wins. Appendix:
