What type of reading does the strategy involving magnetic letters primarily support?

The strategy involving magnetic letters primarily supports the decoding of CVC (consonant-vowel-consonant) words. This hands-on approach allows learners to manipulate letters physically, which can facilitate their understanding of how letters correspond to sounds in speech.

When students engage with magnetic letters, they can form simple words, break words apart, and rearrange letters to see how different sounds combine to create words. This tactile experience is critical for early readers as they learn to decode by sounding out words. By focusing on CVC words, students practice the foundational skills of blending sounds together to read words. This kind of phonemic awareness is essential for developing stronger reading skills, especially in the early stages of literacy development.

In contrast, the other options such as fluency in long texts, comprehension of complex narratives, and summarization of main ideas involve higher-level reading skills that require advanced cognitive processes beyond the foundational skill of decoding simple words. Therefore, the magnetic letters strategy effectively aligns with supporting students in decoding activities, particularly with CVC words.
