Integers:

Learning Objective:
· explain, using concrete materials such as integer tiles and diagrams, that the sum of opposite integers is zero

· illustrate, using a number line, the results of adding or subtracting negative and positive integers (e.g., a move in one direction followed by an equivalent move in the opposite direction results in no net change in position)

· add two given integers using concrete materials or pictorial representations and record the process symbolically

· subtract two given integers using concrete materials or pictorial representations and record the process symbolically

·  solve a given problem involving the addition and subtraction of integers
