### NS: Number Sense

#### NS.1: Students understand the place value of whole numbers:

NS.1.3: Identify the place value for each digit in numbers to 10,000.

NS.1.4: Round off numbers to 10,000 to the nearest ten, hundred, and thousand.

NS.1.5: Use expanded notation to represent numbers (e.g., 3,206 = 3,000 + 200 + 6).

#### NS.2: Students calculate and solve problems involving addition, subtraction, multiplication, and division:

NS.2.1: Find the sum or difference of two whole numbers between 0 and 10,000.

NS.2.2: Memorize to automaticity the multiplication table for numbers between 1 and 10.

NS.2.3: Use the inverse relationship of multiplication and division to compute and check results.

NS.2.6: Understand the special properties of 0 and 1 in multiplication and division.

#### NS.3: Students understand the relationship between whole numbers, simple fractions, and decimals:

NS.3.1: Compare fractions represented by drawings or concrete materials to show equivalency and to add and subtract simple fractions in context (e.g., 1/2 of a pizza is the same amount as 2/4 of another pizza that is the same size; show that 3/8 is larger than 1/4).

NS.3.2: Add and subtract simple fractions (e.g., determine that 1/8 + 3/8 is the same as 1/2).

### AF: Algebra and Functions

#### AF.1: Students select appropriate symbols, operations, and properties to represent, describe, simplify, and solve simple number relationships:

AF.1.5: Recognize and use the commutative and associative properties of multiplication (e.g., if 5 x 7 = 35, then what is 7 x 5? and if 5 x 7 x 3 = 105, then what is 7 x 3 x 5?).

#### AF.2: Students represent simple functional relationships:

AF.2.1: Solve simple problems involving a functional relationship between two quantities (e.g., find the total cost of multiple items given the cost per unit).

AF.2.2: Extend and recognize a linear pattern by its rules (e.g., the number of legs on a given number of horses may be calculated by counting by 4s or by multiplying the number of horses by 4).

### MG: Measurement and Geometry

#### MG.1: Students choose and use appropriate units and measurement tools to quantify the properties of objects:

MG.1.2: Estimate or determine the area and volume of solid figures by covering them with squares or by counting the number of cubes that would fill them.

MG.1.3: Find the perimeter of a polygon with integer sides.

### SDAP: Statistics, Data Analysis, and Probability

#### SDAP.1: Students conduct simple probability experiments by determining the number of possible outcomes and make simple predictions:

SDAP.1.1: Identify whether common events are certain, likely, unlikely, or improbable.

SDAP.1.2: Record the possible outcomes for a simple event (e.g., tossing a coin) and systematically keep track of the outcomes when the event is repeated many times.

SDAP.1.3: Summarize and display the results of probability experiments in a clear and organized way (e.g., use a bar graph or a line plot).

### MR: Mathematical Reasoning

#### MR.1: Students make decisions about how to approach problems:

MR.1.1: Analyze problems by identifying relationships, distinguishing relevant from irrelevant information, sequencing and prioritizing information, and observing patterns.

#### MR.2: Students use strategies, skills, and concepts in finding solutions:

MR.2.1: Use estimation to verify the reasonableness of calculated results.
