MATHEMATICS OBJECTIVE
Students will be able to:
understand how integers, their opposites, and absolute values are related.
apply this understanding to models (number lines) and use these to solve real-world problems.
ESSENTIAL UNDERSTANDING
An integer and its opposite are the same distance from 0 on a number line.
They are on opposite sides of 0 and have a sum of 0.
I can understand how integers, their opposites, and absolute values are related.
I can apply this understanding to models (number lines) and use these to solve authentic applications.
An integer, n, and its opposite, -n, combine to make 0.
4 and -4 are opposites, so they combine to make 0.
[Number line from -7 to 7, indicating -4 and 4, equidistant from zero and in opposite directions.]
