### 3.NSF: Number Sense – Fractions

#### 3.NSF.1: Develop an understanding of fractions (i.e., denominators 2, 3, 4, 6, 8, 10) as numbers.

3.NSF.1.a: A fraction 1/b (called a unit fraction) is the quantity formed by one part when a whole is partitioned into b equal parts;

3.NSF.1.b: A fraction a/b is the quantity formed by 𝑎 parts of size 1/b;

3.NSF.1.c: A fraction is a number that can be represented on a number line based on counts of a unit fraction;

3.NSF.1.d: A fraction can be represented using set, area, and linear models.

#### 3.NSF.2: Explain fraction equivalence (i.e., denominators 2, 3, 4, 6, 8, 10) by demonstrating an understanding that:

3.NSF.2.a: two fractions are equal if they are the same size, based on the same whole, or at the same point on a number line;

3.NSF.2.b: fraction equivalence can be represented using set, area, and linear models;

3.NSF.2.c: whole numbers can be written as fractions (e.g., 4 = 4/1 and 1 = 4/4);

3.NSF.2.d: fractions with the same numerator or same denominator can be compared by reasoning about their size based on the same whole.

### 3.MDA: Measurement and Data Analysis

#### 3.MDA.5: Understand the concept of area measurement.

3.MDA.5.a: Recognize area as an attribute of plane figures;

3.MDA.5.b: Measure area by building arrays and counting standard unit squares;

3.MDA.5.c: Determine the area of a rectilinear polygon and relate to multiplication and addition.

#### 3.MDA.6: Solve real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
