Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Represent and interpret data.

**Standard**:

Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units—whole numbers, halves, or quarters.

#### Standard Identifier: 3.MD.5.a

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Recognize area as an attribute of plane figures and understand concepts of area measurement. A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.

#### Standard Identifier: 3.MD.5.b

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Recognize area as an attribute of plane figures and understand concepts of area measurement. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.

#### Standard Identifier: 3.MD.6

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).

#### Standard Identifier: 3.MD.7.a

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Relate area to the operations of multiplication and addition. 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.

#### Standard Identifier: 3.MD.7.b

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Relate area to the operations of multiplication and addition. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real-world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

#### Standard Identifier: 3.MD.7.c

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Relate area to the operations of multiplication and addition. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.

#### Standard Identifier: 3.MD.7.d

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

**Standard**:

Relate area to the operations of multiplication and addition. Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real-world problems.

#### Standard Identifier: 3.MD.8

Grade:

**3**
Domain:

**Measurement and Data****Cluster**:

Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.

**Standard**:

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.

#### Standard Identifier: 4.MD.1

Grade:

**4**
Domain:

**Measurement and Data****Cluster**:

Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit.

**Standard**:

Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), . . .
