Using known root words as clues to the meaning of unknown words with the same root

General

In this lesson, students will learn how to use root words to figure out unknown words with affixes. They will identify groups of words with the same root words, think of words that contain the same prefixes, and determine the meanings using clues from the root words and affixes.

Standards

CCSS.ELA-Literacy.L.3.4c

Learning objective

Students will be able to use known root words as clues to the meaning of unknown words with the same root.

Introduction

Students will separate words, like "previewed" and "playful," into their affixes and root words. Explain what root words are.

Instruction

Discuss the similarities between the words, "unopened," "opener," and "opening." Students will sort words according to their root words. They will also use a word bank to create more words that start with "tele-." Next, students will read groups of three words, and find the common root words. They will use the root words to help them determine what new words mean. For example, they will fill in: "See means ........... so unseen must mean .........." Then, students will write down the root word that all the words share. From there, they will also write the meanings of those words.

Quiz

Students will respond to ten multiple-choice, short-answer, and open-ended questions.

Closing

Students will recall what they learned:
- How can root words help you with unknown words that have the same root?
- What happens when you add an affix to a root word?

Students will play the game, Pass the Root. They will also find root words in their own books and try to figure out the meanings.
