Introduction

Mixed Number Subtraction ModelsMixed Number Subtraction Model Mat
  • Post a subtraction number sentence for all students to see. Then ask your students to name as many parts of the sentence as possible.
  • Jot student answers for future reference, including the following terms: "minuend," "subtrahend," "subtraction sign," "equal sign," and "difference."
  • Explain the names of three key parts of a subtraction expression:
  • minuend: the amount being subtracted from
  • subtrahend: the amount being subtracted
  • difference: the answer to a subtraction expression

Beginning

  • Allow students to use their home language (L1) or new language (L2) in their discussions.
  • Provide visuals for the key terms and make sure to label the number sentence with the appropriate name for reference.
  • Have students turn and recite the meaning of the words to their partners.

Intermediate

  • Write the academic language students can use throughout the lesson on the board as you introduce the language.
  • Ask them to rephrase the meanings of the new vocabulary to their partner.
