This worksheet has twenty sentences that ask students to select the correct homonym (its or it's). Some instructors like students to write the correct homonym, while others ask students to circle the correct homonym. I provide two versions of the same sentences: one asks students to circle the correct homonym and the other asks students to circle the correct homonym. Essentially, the sentences are the same for both versions.
This worksheet can be used for a practice activity or a quiz.
There is also an answer key attached, totaling three pages.
