NC.3.NBT.2.c: Use expanded form to decompose numbers and then find sums and differences.
NC.3.NF.1: Interpret unit fractions with denominators of 2, 3, 4, 6, and 8 as quantities formed when a whole is partitioned into equal parts;
NC.3.NF.1.a: Explain that a unit fraction is one of those parts.
NC.3.NF.2: Interpret fractions with denominators of 2, 3, 4, 6, and 8 using area and length models.
NC.3.NF.2.b: Using a number line, explain that the numerator of a fraction represents the number of lengths of the unit fraction from 0.
NC.3.NF.3: Represent equivalent fractions with area and length models by:
NC.3.NF.3.a: Composing and decomposing fractions into equivalent fractions using related fractions: halves, fourths and eighths; thirds and sixths.
NC.3.NF.3.b: Explaining that a fraction with the same numerator and denominator equals one whole.
NC.3.NF.3.c: Expressing whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
NC.3.NF.4: Compare two fractions with the same numerator or the same denominator by reasoning about their size, using area and length models, and using the >, <, and = symbols. Recognize that comparisons are valid only when the two fractions refer to the same whole with denominators: halves, fourths and eighths; thirds and sixths.

NC.3.MD.3: Represent and interpret scaled picture and bar graphs:
NC.3.MD.3.a: Collect data by asking a question that yields data in up to four categories.
NC.3.MD.3.b: Make a representation of data and interpret data in a frequency table, scaled picture graph, and/or scaled bar graph with axes provided.
NC.3.MD.3.c: Solve one and two-step “how many more” and “how many less” problems using information from these graphs.
NC.3.MD.5: Find the area of a rectangle with whole-number side lengths by tiling without gaps or overlaps and counting unit squares.
NC.3.MD.7: Relate area to the operations of multiplication and addition.
NC.3.MD.7.a: Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
NC.3.MD.7.b: Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving problems, and represent whole-number products as rectangular areas in mathematical reasoning.
NC.3.MD.7.c: Use tiles and/or arrays to illustrate and explain that the area of a rectangle can be found by partitioning it into two smaller rectangles, and that the area of the large rectangle is the sum of the two smaller rectangles.
NC.3.MD.8: Solve problems involving perimeters of polygons, including finding the perimeter given the side lengths, and finding an unknown side length.
