These spelling strategies center around self-correction techniques that require students to check and correct their own work. Two methods are described: Letter-by-Letter Proofing, where students use proofreading marks to check spelling, and Whole-Word Proofing, where students write corrected misspellings above the original. Both methods use a five-column format for students to write and check words over multiple trials in a 15-20 minute daily lesson.
