### A: Students use numbers in everyday and mathematical contexts to quantify or describe phenomena, develop concepts of operations with different types of numbers, use the structure and properties of numbers with operations to solve problems, and perform mathematical computations. Students develop number sense related to magnitude, estimation, and the effects of mathematical operations on different types of numbers. It is expected that students use numbers flexibly, using forms of numbers that best match a situation. Students compute efficiently and accurately. Estimation should always be used when computing with numbers or solving problems.

#### A.1: Students use factors and multiples.

A.1.a: Identify prime numbers and composite numbers and use their properties to solve problems.

A.1.b: Use the property that every integer greater than one is a prime number or can be written as a unique product of prime numbers.

#### A.4: Students understand how to express relative quantities as percentages and as decimals and fractions.

A.4.b: Use decimals, fractions, and percentages to express relative quantities.

A.4.c: Interpret relative quantities expressed as decimals, fractions, and percentages.

### C: Students use measurement and observation to describe objects based on their sizes and shapes; model or construct two-dimensional and three-dimensional objects; solve problems involving geometric properties; compute areas and volumes based on object properties and dimensions; and perform transformations on geometric figures. When making or calculating measures students use estimation to check the reasonableness of results.

#### C.1: Students represent solid figures in two dimensions.

C.1.a: Represent cubes, prisms, and square-based or triangular-based pyramids using nets.

C.2.a: Triangles

C.2.c: Circles

#### C.4: Students understand and use reflections, rotations, and translations to define and identify congruent plane figures.

C.4.a: Apply the understanding that if a plane figure can be laid on top of another plane figure by rotations, translations, or reflections then the figures are congruent.

### D: Students use symbols to represent or model quantities, patterns, and relationships and use symbolic manipulation to evaluate expressions and solve equations. Students solve problems using symbols, tables, graphs, and verbal rules choosing the most effective representation and converting among representations.

#### D.1: Students create and evaluate expressions.

D.1.a: Create and evaluate expressions using whole numbers.

D.1.b: Create and evaluate expressions using positive fractions including decimals.

#### D.2: Students recognize and solve problems involving linear equations and recognize examples and non-examples of linear equations.

D.2.a: Solve equations of the form ax +/- b = c where a, b, and c are whole numbers.

D.2.b: Recognize from a table whether a relationship has a constant rate of change.

#### D.3: Students use tables, formulas, diagrams, and graphs to analyze relationships between quantities.

D.3.a: Use tables, formulas and graphs to analyze constant difference (additive) relationships.
