- 6.NS.5. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.||Common Core Mathematics||Grade 6||The Number System||Apply And Extend Previous Understandings Of Numbers To The System Of Rational Numbers
