This Instructional Activity is a part of the Lesson 1, Unit 2, Grade 7. Students add positive integers by counting up and negative integers by counting down (using curved arrows on the number line). Students play the Integer Game to combine integers, justifying that an integer plus its opposite add to zero. Students know the opposite of a number is called the additive inverse because the sum of the two numbers is zero.
