#### MA8.1: Students use numbers, number sense, and number relationships in a problem-solving situation.

MA8.1.1: Students represent and apply numbers in a variety of equivalent forms (such as changing from percent to decimal to fraction, etc.) and in a problem-solving context:

MA8.1.1.a: prime factors, factors, and multiples;

MA8.1.1.b: rational numbers and proportions; and

MA8.1.1.c: square roots and powers.

MA8.1.2: Students extend understanding and use of basic arithmetic operations on rational numbers.

MA8.1.2.a: Simplify numerical expressions using the order of operations;

MA8.1.2.b: Order rational numbers expressed in a variety of forms

MA8.1.3: Students explain their choice of estimation and problem- solving strategies and justify results of solutions in problem-solving situations involving rational numbers.

MA8.1.4: Students understand properties of operations with rational numbers.

#### MA8.2: Students apply geometric concepts, properties, and relationships in a problem-solving situation.

MA8.2.1: Students classify and describe one-, two-, and three-dimensional geometric objects, including:

MA8.2.1.a: lines, rays, segments, and angles;

MA8.2.1.c: circles and spheres;

MA8.2.1.d: regular polygon types;

MA8.2.3: Students use geometric formulas including the Pythagorean Theorem.

#### MA8.3: Students use a variety of tools and techniques of measurement in a problem-solving situation.

MA8.3.1: Students apply estimation and measurement of weight/mass to content problems and convert within U.S. customary and within metric units (mg, g, kg).

MA8.3.2: Students apply estimation and measurement of capacity/volume to content problems and convert within metric units (ml, l).

MA8.3.3: Students select and use the appropriate methods, tools, and units to solve problems involving angle measure, perimeter, circumference, area (including circles), and volume of rectangular solids.

#### MA8.4: Students use algebraic methods to investigate, model, and interpret patterns and functions involving numbers, shapes, data, and graphs in a problem-solving situation.

MA8.4.1: Students translate word phrases, which involve the four basic operations to mathematical expressions.

MA8.4.2: Students solve one- and two- step linear equations each with an integer coefficient and integer solutions.

MA8.4.4: Using simple linear equations, students create a table, and graph the solutions on the coordinate system.

#### MA8.5: Students use data analysis and probability to analyze given situations and the results of experiments.

MA8.5.1: Students systematically collect, organize, describe, analyze, and represent data using tables, charts, diagrams, and graphs.

MA8.5.2: Students calculate mean, median, mode, and range for data sets and use in a real-world setting appropriate to grade level.

MA8.5.3: Students predict, compare, and calculate probable outcomes of experiments or simulations.

MA8.5.4: Students communicate about the likelihood of events using concepts from probability such as impossible, equally likely and certain appropriate to grade level.
