This Grade 2 worksheet introduces prefixes and suffixes by sorting words into two groups. Students decide if a word has a prefix at the beginning, such as unlock or redo, or a suffix at the end, such as helpful or slowly. Fill-in-the-blank items check simple meanings like un- means not and -ful means full of. True-or-false questions ask Grade 2 readers to confirm that prefixes go at the start while suffixes go at the end.
