How to teach this

Shift from mnemonics to jobs: which part of speech does this blank need? A noun slot can't take accept; a verb slot can't take effect (usually). Middle schoolers who ask what job the sentence is hiring for stop being fooled by sound-alikes, in essays as well as on sheets.

Watch for: Spellcheck won't catch these: 'there boots' is spelled correctly, it's just the wrong word. The apostrophe versions are always two words squeezed together: they're = they are, you're = you are, it's = it is. Expanding them is the test.

Common questions about commonly confused words

Why do these pairs still deserve practice in 6th grade?
Because spell-check can't catch them; every option is a real, correctly spelled word. As writing gets more formal, these become the errors that survive to the final draft. A sixth grader with clean confusables reads instantly more credible.
How do I help without just giving answers?
Ask for the sentence's job description: does this blank need a thing, an action, or a describer? Then ask which candidate does that job. It turns each item into a two-step reasoning problem, which is the durable skill under the memorized pairs.
