For the words affect and effect, it's helpful to remind students that affect is typically used as a verb, as in "Practicing Rocket Spelling positively affects your spelling skills." The word effect, by contrast, is generally used as a noun. "Learning to spell well has a positive effect on students' confidence."
Some people like the RAVEN acronym to remember the difference between affect and effect. Remember: Affect is a Verb; Effect is a Noun.
