CCR Focus Standards

Number and Ratios - Level D

• 7.NS.2

  Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.

Supporting Standards

• 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.

• 6.NS.6a

  Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.
