Grade 7 - Number
Standard 7.N.6 - Practice evaluating multi operation expressions with integers.
Included Skills: Mixed Equations
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.
