Lose and loose, accept and except, their, there, and they're look and sound almost alike, so a fourth grader cannot tell them apart by sound the way they can with most words — they have to think about what each word means and check it against the sentence. This worksheet always shows a complete sentence with one blank, never the pair of confusable words sitting side by side with no context, because that is exactly the reasoning a real writer has to do. Some questions ask which word completes the sentence, others ask what the correct word means there, and others ask your child to type the word themselves rather than choose it from a list.
The most common mistake is picking the more familiar-looking or more frequently seen word out of habit rather than checking its meaning. Ask your child to say what each word in the confusable pair means before they choose, since the meaning almost always settles which spelling belongs in the blank.
What your child will learn
Choose the correct word between commonly confused pairs
Explain what each word in a confusable pair means
Recognize a correctly used sentence versus an incorrect one
Spell the correct word from context without a word bank
Worked example
"Tighten your shoelace before it comes completely loose" needs loose, meaning not tight, while lose means to misplace something.
Common mistake
Picking the more familiar-looking word out of habit instead of checking what each word actually means.
Helpful hint
Say what each word in the pair means, then decide which meaning fits the sentence.
