# K.NR.4: Numbers to 20

Identify, write, represent, and compare numbers up to 20.

- Subject: Mathematics
- Appears in: Kindergarten, https://georgiahomeroom.org/standards/math/kindergarten.md

## Expectations

- **K.NR.4.1**: Identify written numerals 0- 20 and represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
- **K.NR.4.2**: Compare two sets of up to 10 objects and identify whether the number of objects in one group is more or less than the other group, using the words “greater than,” “less than,” or “the same as”.

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.

## The same standard across grades

- **Kindergarten, K.NR.4 (this standard)**: Identify, write, represent, and compare numbers up to 20.
- Grade 3, 3.NR.4: Represent fractions with denominators of 2, 3, 4, 6 and 8 in multiple ways within a framework using visual models. https://georgiahomeroom.org/standards/code/3.NR.4.md
- Grade 4, 4.NR.4: Solve real-life problems involving addition, subtraction, equivalence, and comparison of fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12, and 100 using part-whole strategies and visual models. https://georgiahomeroom.org/standards/code/4.NR.4.md
- Grade 5, 5.NR.4: Read, write, and compare decimal numbers to the thousandths place, and round and perform operations with decimal numbers to the hundredths place to solve relevant, mathematical problems. https://georgiahomeroom.org/standards/code/5.NR.4.md
- Grade 6, 6.NR.4: Solve a variety of contextual problems involving ratios, unit rates, equivalent ratios, percentages, and conversions within measurement systems using proportional reasoning. https://georgiahomeroom.org/standards/code/6.NR.4.md
