The document discusses a three-tier classification system for vocabulary words in mathematics - Tier I words are basic words that rarely need instruction, Tier II words are frequently used and important for comprehension, and Tier III words are low frequency and specialized terms that should be taught when they arise in content. It provides guidance on identifying Tier II words that require explicit instruction based on likelihood of student knowledge and importance for comprehension, and identifying Tier III words based on frequency and specialization to content.

3. Tier I Basic words Examples: the, and, was, cat Rarely require instruction CORE Vocabulary Handbook : Linda Diamond and Linda Gutlohn
4. Tier II Frequently used words Central to comprehension Explicit instruction Questions: Are students unlikely to know this word’s meaning? Is the meaning of the word important for students’ comprehension of the text being read? CORE Vocabulary Handbook : Linda Diamond and Linda Gutlohn
5. Tier III Low frequency words Specialized words Content specific Should be taught as they arise Is it a word whose meaning students are unlikely to know?
