Final answer:
A new irregular word should not be introduced to students until they are well-acquainted with the original set of irregular words they are learning.
Step-by-step explanation:
During the time when students are learning their first 10 irregular words, a new irregular word should not be introduced until they have a firm grasp of the original set. The process of acquiring irregular words can be complex due to their lack of phonetic consistency and the need for memorization. It is beneficial for students to have enough time to practice and internalize these words before encountering additional ones, as this helps in building a strong foundation for reading and writing.
