  • Gather the class together and write base-ten numeral, expanded form, and number name on the whiteboard.
  • Read each word aloud and ask students to think about the meaning of each word. Have students think-pair-share their ideas and provide sentence stems and frames to support their ideas, such as:
    • I notice ________.
    • I think ________ means ________ because ________.
  • Allow a few students to share their ideas. Encourage them to come up to the whiteboard to act as the teacher. Encourage students to create visuals, words, and phrases next to the vocabulary words if they feel comfortable. Ask prompting questions to elicit more meaningful feedback.
  • Explain to the students that today they will be learning about different number forms. Read the language objective in student-friendly language and define any words within the objective that may be unfamiliar. Ask students to restate word meanings in their own words to check for understanding.
