31. A classroom teacher posts three cards on which are written the words 'joyless,' 'careless,' and 'senseless.' The teacher goes through each word with students, guiding them to notice the repeated word part and what the meanings of the words have in common. As students encounter words that share similar qualities, they add them to a bulletin board. The activity best helps students decode unfamiliar words by teaching them to
Answer: C
Students decode unfamiliar words by recognizing how affixes give clues to the meaning of words with familiar base words.
This activity enables students to understand how affixes, such as prefixes and suffixes, modify the meanings of base words they already know. By examining words like 'joyless,' 'careless,' and 'senseless,' students can identify the base word 'less' and comprehend how it alters the meaning.
A) recognize how common roots give clues about the meaning of words
While recognizing common roots is beneficial for understanding word meanings, this option does not accurately reflect the focus of the activity, which centers on the role of affixes. The words discussed primarily illustrate how affixes change meaning rather than emphasizing the root alone.
B) use the origin of root words to predict the meanings of unfamiliar words
This choice suggests a historical understanding of word origins, but the activity is not focused on etymology. Instead, it emphasizes the application of understanding affixes to interpret unfamiliar words, making this option less relevant to the teacher's objective.
C) recognize how affixes give clues to the meaning of words with familiar base words
This option accurately captures the essence of the activity, as students analyze how the suffix '-less' modifies the meanings of the base words 'joy,' 'care,' and 'sense.' By recognizing these affixes, students can derive meanings of new words they encounter, which is the primary goal of the exercise.
D) use the definitions of previously learned words to define newly encountered words
Although using known word definitions can help in understanding new words, this option does not directly relate to the specific focus on affixes in the discussed activity. The lesson targets students' abilities to decode meanings through the understanding of affixes rather than just relying on previously learned definitions.
Conclusion
The correct answer highlights the critical role that affixes play in word meaning and aligns perfectly with the teacher's instructional approach. Options A, B, and D misinterpret the focus on affixes or do not directly apply to the lesson's structure, making them unsuitable. Thus, recognizing affixes is essential for effective word decoding, showcasing why option C is the most appropriate choice.
