Lesson Plan: Suffixes

Subject:  ELA- Reading

Grade: 3

Lesson Objective: To learn about common suffixes and demonstrate an understanding of them

Common Core Standard:  CCSS.ELA-LITERACY.RF.3.3.B- Decode words with common Latin suffixes.

Materials:

Starter:

Say:

  • What is the difference between the words end and endless?  (Allow the students to answer.)

Main:

Say:

  • The word end means that there is something that stops eventually.  The word endless means that there is no end or the thing does not ever stop.
  • Behind the word end are the letters “less.”  “Less” is a suffix. 
  • A suffix is a word or a group of letters that change the meaning of a word.
  • There are many different suffixes.  We are going to talk about 4 of those suffixes today.
  • The suffixes that we are going to talk about are -er, -ly, -ful and -less. (Write the prefixes on the board and point to them as you talk about them.)
  • The suffix -er is a way to compare something.  For example, if you have the word small and then add an -er to the end, the word is smaller, which means littler. 
  • The suffix -ly changes the meaning of the word to a characteristic, or a way to describe something.  For example, using the word beautiful, when you add an -ly to the end, the word is beautifully.  This means that something was done in a very pretty way.
  • The suffix -ful means full of.  The word painful means something that is full of pain.
  • The suffix -less means without.  The word painless means something without pain.
  • Now, you are going to be doing a worksheet so that you can practice what you learned about suffixes.  You will see the suffix and then two words with a blank next to each.  Figure out which word works best with the suffix.  Then, add the suffix to that word by writing the word with the suffix on the line.
  • Does anyone have any questions?

Feedback:

Say:

  • Who would like to share their answers?  (Allow the students to share and go over the answers.)
