Grade 6th

Students` Learning Outcomes

  • Recognize specific parts of words, including common inflectional endings, compound words and affixes.

Information for Teachers

  • This lesson is a continuation of the previous lesson about compound words and prefixes.


  • In this lesson we will focus on suffixes separately and practice an exercise on affixes.
  • Affixes: prefixes and suffixes together are called affixes.



  • When letters are added at the beginning of a root word to make a new word we call it prefix, such as;



  • When letters are added to the end of a root / base word to make a new word we call them suffixes, as such;



  • Root word or base word is the main word on which inflection is done or to which we add prefixes or suffixes.



  • While teaching the lesson, the teacher should also consult textbook at all steps where and when applicable.


Material / Resources

Writing board, chalk / marker, duster, textbook, flashcards of root words and suffixes 


  • Sample flashcards have been given at the end of lesson plan.
  • Arrange photocopies of worksheets for all the students or make the worksheets on the paper and paste in the class.
  • Make all flashcards like the sample made above.


  • Hold a pencil in your hand and ask students, ‘What am I holding?’
  • Write the word ‘pencil’ on the board.
  • Hold another pencil in your hand and repeat the question.
  • Write ‘pencils’ on the board in coloured chalk against the word ‘pencil’.
  • Ask a student to jump in the class.
  • Write the word jump on the board.
  • Ask the students, ‘What did he do? Or ‘What was he doing?’ expected answer would be as; he jumped or he was jumping. Write the words ‘jumping’ and ‘jumped’ against the word jump on the writing board.
  • Underline ‘ing’ in jumping word and ‘ed’ in jumped word with coloured chalk.
  • Inform the class that new words can be made by adding some letters at the END of the root words. These letters are called suffixes.
  • Ask them to give a few examples of such type of words.


Activity 1

  • Paste the flashcards on the board. (Flashcards for suffixes are given at the end of the plan).
  • Ask the students to pronounce the words.
  • Teach the students that some root words will change spelling when a suffix is added to them e.g. beauty + full = beautiful.
  • Teach them that the last ‘l’ of ‘full’ runs away when it is added to a root word such as; beautiful.
  • Students will write more words in their notebooks.

Activity 2

  • Students can do the following worksheet for further reinforcement.


Sum up / Conclusion

  • Ask students the function of the inflections / suffixes and definition of compound words. Why do we add ‘s’, ‘es’, ‘ed’ and ‘ing’ at the end of words? Give some suffixes and their root words.
  • Find the exercise related to the topic in the textbook
  • Students must do this exercise in the notebook or on the textbook


  • Ask them to give 10 examples of suffixes and prefixes.
  • Assess students` understanding through responses and written work.
  • Involve the students in solving problems given in the exercise at the end of unit / chapter of the textbook

Follow up

  • In your notebooks write, five actions you did in the evening (words ending in ‘ed’,’ ing’) underline the root word and circle the inflection in each action.
  • Find things from your house (words ending in‘s’ and ‘es’). Underline and identify the root word and circle the inflection in each action.
  • Write five words with suffixes.
