This is the first of four consecutive levels that practice homophones. We've included both words in each pair so that students will have to rely on context to determine the proper spelling.
It's important to note that for the word its, one might expect it to have an apostrophe because it shows ownership, but like other possessive pronouns (such as his, hers, ours, mine, theirs, and yours), its has no apostrophe. All of those possessive pronouns can be tricky for students!
