Using Positive and Negative Numbers in Context

This lesson unit is intended to help you assess how well students are able to understand and use directed numbers in context. It is intended to help identify and aid students who have difficulties in ordering, comparing, adding, and subtracting positive and negative integers. Particular attention is paid to the use of negative numbers on number lines to explore the structures:

starting temperature + change in temperature = final temperature
final temperature – change in temperature = starting temperature
final temperature – starting temperature = change in temperature
