Task# Temperature Change

Illustrative MathematicsVaries

The goal of this task is to provide a context for interpreting the expressions -(p/q), (-p)/q, and p/(-q ): this matches the last part of the standard 7.NS.2.b, 'Interpret quotients of rational numbers by describing real-world contexts,' though in this case the numerator and denominator are integers. Because of the context, students will also gain experience working with rates. Each expression calculates the rate for the change in temperature over the three hour period and this means that the three expressions must be equal.
