# 2.NR.2: Addition & Subtraction within 1,000

Apply multiple part-whole strategies, properties of operations and place value understanding to solve real-life, mathematical problems involving addition and subtraction within 1,000.

- Subject: Mathematics
- Appears in: Grade 2, https://georgiahomeroom.org/standards/math/grade-2.md

## Expectations

- **2.NR.2.1**: Fluently add and subtract within 20 using a variety of mental, part-whole strategies.
- **2.NR.2.2**: Find 10 more or 10 less than a given three-digit number and find 100 more or 100 less than a given three-digit number.
- **2.NR.2.3**: Solve problems involving the addition and subtraction of two-digit numbers using part-whole strategies.
- **2.NR.2.4**: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
