1.NR Numerical Reasoning
- 1.NR.4 Represent partitioned shapes in multiple ways using part-whole relationships
  - 1.NR.4.1 Partition in multiple ways squares, rectangles, and circles into two or four equal-sized parts. Name the pieces as halves and fourths
2.NR Numerical Reasoning
- 2.NR.4 Represent and compare partitioned shapes in multiple ways using part-whole relationships
  - 2.NR.4.1 Partition in multiple ways squares, rectangles, and circles into two or four equal sized parts, and describe the parts using the words halves, fourths, a half of, and a fourth of (not quarters)
  - 2.NR.4.2 Explain that when partitioning a square, rectangle, or circle into two or four equal parts, the parts become smaller as the number of parts increases
