Final answer:
The best activity to help students divide multisyllabic words into syllables is marking off syllables using a dot between vowels and consonants. This visual and auditory activity helps students recognize the separate syllables in a word, assisting them with decoding skills. Correct option is A.
Step-by-step explanation:
When helping students divide multisyllabic words into syllables, the best activity is to mark off syllables using a dot between vowels and consonants. This visual cue helps students to identify the separate syllables in a word. For example, in the word 'anchor,' the syllables can be marked as 'an.chor.' This activity allows students to visually and audibly recognize the syllables in a word, helping them develop their decoding skills.
