English
This Grade 2 English worksheet helps students understand how the prefixes un- and dis- change the meaning of base words. Through 20 questions—one multiple-select item and 19 multiple-choice items—students identify that prefixes come at the beginning of words, explain that un- and dis- can mean “not” or “opposite of,” and determine the meanings of words such as unhappy, dishonest, and untidy. Students also identify base words in words such as unzip and disobey, choose the appropriate prefix for words including kind and lucky, and apply prefix knowledge in context. The mix of definition, word-part analysis, meaning, and application questions supports early morphology and vocabulary instruction. This free printable worksheet includes an answer key, making it suitable for independent practice, guided review, homework, or a quick Grade 2 English skills check.

This Grade 2 English worksheet teaches students to recognize un- and dis- as prefixes that can mean “not” or “opposite of” and to notice that a prefix comes at the beginning of a word. Its 20 multiple-select and multiple-choice questions ask students to interpret words such as unhappy, dishonest, and untidy, identify base words in unzip and disobey, and choose a suitable prefix in context.
Introduce the worksheet by modeling how to separate a prefix from its base word, such as un- plus zip or dis- plus obey. Then have students explain how adding the prefix changes the meaning of words such as happy, honest, and tidy before completing the multiple-choice items. Use the prefix-selection questions as a discussion point: ask students why un- fits words such as kind and lucky and how the resulting word changes meaning.
Students may choose a prefix based only on its appearance, use dis- for every word that means “not,” or confuse the prefix with the base word—for example, selecting dis or ey instead of obey in disobey. They may also identify the prefix as being at the end or middle of a word, or misread unhappy and untidy as positive meanings. Ask students to remove the prefix and say the remaining base word, then explain the new word’s meaning.
