- **K.NR.5.4**: Fluently add and subtract within 5 using a variety of strategies to solve practical, mathematical problems.

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.

## The same standard across grades

- **Kindergarten, K.NR.5 (this standard)**: Explain the concepts of addition, subtraction, and equality and use these concepts to solve real-life problems within 10.
- Grade 1, 1.NR.5: Use concrete models, the base ten structure, and properties of operations to add and subtract within 100. https://georgiahomeroom.org/standards/code/1.NR.5.md
- Grade 4, 4.NR.5: Solve real-life problems involving addition, equivalence, comparison of fractions with denominators of 10 and 100, and comparison of decimal numbers as tenths and hundredths using part-whole strategies and visual models. https://georgiahomeroom.org/standards/code/4.NR.5.md
- Grade 5, 5.NR.5: Write, interpret, and evaluate numerical expressions within authentic problems. https://georgiahomeroom.org/standards/code/5.NR.5.md
