**Type of items:**Type 1

**Color Code:**Peach

**Evidence Statement Key:**7.NS.1b-2

**Calculator:**No

**Point:**1 each (1:29)

**Evidence Statement Text:**

Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. b. Interpret sums of rational numbers by describing real-world contexts.

**Clarifications, limits, emphases, and other information intended to ensure appropriate variety in tasks:**

1. Tasks require students to produce or recognize real-world contexts that correspond to given sums of rational numbers.

2. Tasks are not limited to integers.

3. Tasks do not require students to show in general that a number and its opposite have a sum of 0; for this aspect of 7.NS.1b-1, see 7.C.1.a and 7.C.2
