Introduction
(5 minutes)- Post a subtraction number sentence for all students to see. Then ask your students to name as many parts of the sentence as possible.

- 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.
