Objectives:

Students will comprehend the function of prefixes and how they alter the meaning of base words.
Students will recognize and utilize the prefixes un-, re-, and dis- to construct words.
Students will engage in reading and writing words containing these prefixes in their spelling list.

Materials:
Whiteboard
Visual aids (examples of words with un-, re-, and dis- prefixes)
Spelling word list:

  • undo
  • redo
  • dislike
  • disloyal
  • refill
  • unkind
  • reread
  • unlike
  • remove
  • dishonest
  • unhappy
  • rebuild
  • displease
  • uncover
  • rewrite

Introduction (5 minutes):

Define prefixes as sets of letters added to the beginning of base words to change their meaning. Emphasize that prefixes alter the sense of words.
Explain that today’s focus is on prefixes un-, re-, and dis- and their impact on base words.

Explain that the prefix un- means “not”. (e.g. If we add the letters u-n to the word able, it turns into the word unable. Unable means not able.)
Explain that the prefix re- means “again”. (e.g. If we add the letters r-e to the word play, it turns into the word replay. Replay means play again.)
Explain that the prefix dis- means “opposite of”. (e.g. If we add the letters d-i-s to the word honest, it turns into the word dishonest. Dishonest is the opposite of honest, so it means not honest.)

Theocratic Connections:

Understanding prefixes and word structures can facilitate comprehension of texts encountered in the Bible.

Activity 1 – Introduction to Prefixes (7 minutes):

Present examples of base words and their corresponding words with prefixes on the whiteboard. Practice identifying and pronouncing the prefixes un-, re-, and dis-.

Activity 2 – Practice with Prefixes (7 minutes):

Show examples of words with un-, re-, and dis- prefixes and discuss their meanings. Practice forming words by adding these prefixes to base words.

Activity 3 – Application of Prefixes  (7 minutes):

Present examples of words with un-, re-, and dis- prefixes used in sentences. (You can create sentences and/or use biblical examples.) Practice constructing sentences using words with these prefixes, focusing on their altered meanings.

Conclusion (2 minutes):

Summarize key points: Prefixes are added to base words to change their meanings. Today, we focused on the prefixes un-, re-, and dis-, learning how they alter words. Encourage students to practice reading and writing words with these prefixes to reinforce their understanding.

Assessment:

Informally assess students through participation in prefix identification activities, their ability to form words with prefixes, and their comprehension of the meanings conveyed by words with prefixes.
