Standard 7.N.6 - Determine if an integer equation is positive or negative.

Included Skills:

Demonstrate an understanding of addition and subtraction of integers, concretely, pictorially, and symbolically.
• Represent opposite integers concretely, pictorially, and symbolically and explain why they are called opposite integers.
• Explain, using concrete materials such as integer tiles and diagrams, that the sum of opposite integers is zero (e.g., a move in one direction followed by an equivalent move in the opposite direction results in no net change in position).
• Illustrate, using a number line, the results of adding or subtracting negative and positive integers.
• Add two integers using concrete materials or pictorial representations and record the process symbolically.
• Subtract two integers using concrete materials or pictorial representations and record the process symbolically.
• Investigate patterns in adding and subtracting integers to generalize personal strategies for adding and subtracting integers.
• Solve problems involving the addition and subtraction of integers.
