Essential Understanding
Adding integers requires adding (if the signs are the same), or subtracting (if the signs are different) their absolute values and understanding the sign of the sum.
Standards7.NS.A.1b Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
7.NS.A.1d Apply properties of operations as strategies to add and subtract rational numbers. |
