  • Ask students and turn to a partner and discuss the term subtract. Ask them to think of how they would explain the concept of subtraction to someone that does not know the meaning. Ask them to think of keywords or phrases that relate to subtraction (e.g., "take away," "difference," "how many are left").
  • Have students share their responses with a whole group and document their background knowledge on a piece of chart paper. Leave the chart paper on display for the rest of the lesson.
