Task

Comparing Freezing Points

Illustrative MathematicsVaries

This task is appropriate for assessing student's understanding of differences of signed numbers. Because the task asks how many degrees the temperature drops, it is correct to say that 'the temperature drops 61.5 degrees.' However, some might think that the answer should be that the temperature is 'changing -61.5' degrees. Having students write the answer in sentence form will allow teachers to interpret their response in a way that a purely numerical response would not.
