Student Actions	Teacher Actions

Students will use knowledge of prefixes, suffixes, and root words to determine the meaning of unknown words.	Teachers explain word parts: root words, prefixes, and suffixes. Teachers explain meanings of common word parts (roots, prefixes and suffixes). Teachers model reading words with common word parts (roots, prefixes, and suffixes) and how to use the parts to determine the meanings of the words. Teachers provide opportunities for students to apply knowledge of common roots, prefixes, and suffixes to determine the meanings of unknown words. Teachers monitor and provide opportunities for students to receive feedback as they define new words.

Most Used Commonly Used Prefixes and Suffixes Greek and Latin Roots (Website) Center for Development and Learning Common Prefixes/Suffixes (website)	Affix is a morpheme or meaningful part of a word attached before or after a root to modify its meaning. Principal kinds of affixes are prefixes and suffixes. Affix is the broad category for prefix and suffix. The prefix un- is an affix, which added to balanced, makes unbalanced. The suffix -ed is an affix which added to wish, makes wished. Stem is the base form of a word, also called the root word. Examples of a stem (or root word): jump, walk, run. Root is a bound morpheme, usually of Latin origin, that cannot stand alone but is used to form a family of words with related meanings. Examples of a root: photo, bio, phobia, micro, auto Example: biology = bio- is a root and -ology is a suffix. Base is a free morpheme to which affixes can be added, usually of Anglo-Saxon origin. Root words do not stand alone, base words do. Example: unhappy = un- is a prefix and happy is a base. The intent of this standard is to focus on how affixes contribute to the meaning of a base word, not just to memorize a list of prefixes, suffixes, and root words.
Due to recursive nature of the standards, it is essential that teachers are aware of how all objectives within and between strands work together for optimal instruction.
