Final answer:
Teachers should follow guidelines when choosing key words for sound spelling cards such as selecting words with common sounds and visual appeal while avoiding words with irregular spellings.
Step-by-step explanation:
When choosing key words for sound spelling cards, teachers should consider the following guidelines:
- Choose words with common sounds: Key words should represent sounds that students encounter frequently in their reading and writing. Examples include words like 'cat', 'dog', and 'book'.
- Choose words with visual appeal: Key words should be visually engaging and attract the attention of students. An example could be 'rainbow' or 'butterfly'.
