Your sixth and seventh graders deepen their understanding of a number line and adding integers in this concrete, hands-on activity. Learners play "Warehouse Puzzle" and then discuss their game strategies and the characteristics of negative numbers. Then they label a life-size number line with equally spaced positive and negative numbers mirrored around zero. Then some real-life thermometer scenarios further the conceptual understanding of positive and negative numbers and their operations.
