About This Lesson
Help students choose addition or subtraction from the meaning of a story, then explain their reasoning with a number sentence and a unit. This original HotMathGames pack includes two student activity pages (16 problems within 20), an answer key, and a one-page teacher guide.
Suggested lesson (30 minutes): launch with an apple story; model an addition and a subtraction problem; solve two together using counters or a number line; let students work independently; discuss how the story guides the operation. The guide includes support, stretch prompts, and an exit ticket.
Grades: 1-2. Subject: Math / Operations and Algebraic Thinking. Print the student pages for class and keep the answer key for review.
