### NS: Number Sense

#### NS.1: Students compute with very large and very small numbers, positive integers, decimals, and fractions and understand the relationship between decimals, fractions, and percents. They understand the relative magnitudes of numbers:

NS.1.1: Estimate, round, and manipulate very large (e.g., millions) and very small (e.g., thousandths) numbers.

NS.1.4: Determine the prime factors of all numbers through 50 and write the numbers as the product of their prime factors by using exponents to show multiples of a factor (e.g., 24 = 2 x 2 x 2 x 3 = 2³ x 3).

NS.1.5: Identify and represent on a number line decimals, fractions, mixed numbers, and positive and negative integers.

#### NS.2: Students perform calculations and solve problems involving addition, subtraction, and simple multiplication and division of fractions and decimals:

NS.2.1: Add, subtract, multiply, and divide with decimals; add with negative integers; subtract positive integers from negative integers; and verify the reasonableness of the results.

NS.2.3: Solve simple problems, including ones arising in concrete situations, involving the addition and subtraction of fractions and mixed numbers (like and unlike denominators of 20 or less), and express answers in the simplest form.

### AF: Algebra and Functions

#### AF.1: Students use variables in simple expressions, compute the value of the expression for specific values of the variable, and plot and interpret the results:

AF.1.1: Use information taken from a graph or equation to answer questions about a problem situation.

AF.1.5: Solve problems involving linear functions with integer values; write the equation; and graph the resulting ordered pairs of integers on a grid.

### MG: Measurement and Geometry

#### MG.1: Students understand and compute the volumes and areas of simple objects:

MG.1.3: Understand the concept of volume and use the appropriate units in common measuring systems (i.e., cubic centimeter [cm³], cubic meter [m³], cubic inch [in³], cubic yard [yd³]) to compute the volume of rectangular solids.

MG.1.4: Differentiate between, and use appropriate units of measures for, two- and three-dimensional objects (i.e., find the perimeter, area, volume).

#### MG.2: Students identify, describe, and classify the properties of, and the relationships between, plane and solid geometric figures:

MG.2.1: Measure, identify, and draw angles, perpendicular and parallel lines, rectangles, and triangles by using appropriate tools (e.g., straightedge, ruler, compass, protractor, drawing software).

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

#### SDAP.1: Students display, analyze, compare, and interpret different data sets, including data sets of different sizes:

SDAP.1.1: Know the concepts of mean, median, and mode; compute and compare simple examples to show that they may differ.

SDAP.1.2: Organize and display single-variable data in appropriate graphs and representations (e.g., histogram, circle graphs) and explain which types of graphs are appropriate for various data sets.

SDAP.1.4: Identify ordered pairs of data from a graph and interpret the meaning of the data in terms of the situation depicted by the graph.

SDAP.1.5: Know how to write ordered pairs correctly; for example, (x, y).

### 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.

#### MR.3: Students move beyond a particular problem by generalizing to other situations:

MR.3.1: Evaluate the reasonableness of the solution in the context of the original situation.
