UNIT X 246 | UNIT 7 Instructional Routine: Vocabulary p. Txxiii Vocabulary in Context • Preview vocabulary Remind students of the vocabulary strategies they have learned, such as Use Visuals, Word Web, and Personalize Vocabulary. Have students preview new vocabulary by pointing out the terms and choral reading them. Say: Which of these words do you know? Ask volunteers to share responses. • Use images to clarify word meanings Have volunteers read the example sentences and discuss what they see in the images to aid comprehension. After each sentence, ask: What do you see in this picture? Does the sentence and picture help you understand the word? Use the vocabulary routine to teach any unfamiliar words. • Classify words Draw a chart on the board with the heads noun, verb, adjective. Call on volunteers to write a vocabulary word in the correct column. Direct students to refer to the example sentence to determine the part of speech of each word. (noun: ecosystem, precipitation; verb: depend on, migrate, hibernate; adjective: frozen, arid, nocturnal, humid) • Play a vocabulary game Have students create sets of vocabulary cards and definition cards. For example, for the first word, create a vocabulary card with the word ecosystem and a definition card with the phrase all the plants and animals in one area. Then divide students into pairs and combine their sets of cards. Pairs turn all the cards face down and take turns choosing one picture card and one definition card to try to make matches. The student with the most matched pairs wins. EXPLORE AND LEARN DIFFERENTIATED INSTRUCTION Scaffold Some of the new vocabulary may be challenging for students, especially scientific terms. It can be helpful to provide a short definition. Display this sentence frame: _____ means _____. After reading the vocabulary items and example sentences, write a short definition, eliciting student input where possible. Encourage students to copy the words and definitions in their notebooks. Amplify To make the vocabulary game more challenging, after students pick up two matching cards, have them make a new original sentence with it. For example, after picking up the vocabulary card ecosystem and the definition card, the student can say: The forest is an example of an ecosystem.
