Common Misconceptions & Diagnostics
Fragment Confusion: Students often identify fragments as full sentences if they are long. Remind them to check for a "doing word" (verb). If nobody is doing anything, the case is cold! Syllable Splitting: Ensure students split between two consonants when applicable (e.g., shad-ow vs sha-dow are both phonetically helpful, but standard dictionary division is shad-ow. Accept logical phonetic breaks that support spelling success).
