# Mathematics Eighth grade mathematics instruction will focus on formulating expressions and equations, grasping the concept of a function to describe quantitative relationships, analyzing two- and three-dimensional figures using distance, angle, similarity, and congruence, and applying the Pythagorean Theory.

Algebra

• Solve literal equations for a specified variable

• Graph one- and two-step inequalities in one variable

• Define, evaluate, and compare functions

• Use functions to model relationships between quantities

Number and Operations

• Know that there are numbers that are not rational, and approximate them by rational numbers

• Use exponents and scientific notation to write large and small numbers and solve problems

• Make reasonable approximations of square roots

• Perform operations on real numbers (including integer exponents, radicals, percentages, scientific notation, absolute value, rational numbers, and irrational numbers) using multi-step and real-world problems.

Geometry

• Compare, contrast, and convert units of measure between measurement systems and dimensions (including temperature, area, volume, and derived units) to solve problems.

• Understand congruence and similarity using physical models, transparencies, or geometry software

• Understand and apply the Pythagorean Theory

Data Analysis

• Investigate patterns of association in bivariate data Assessment: The School will employ authentic assessment techniques to assess student

achievement of the NGSSS math standards in addition to state-mandated assessments. This will allow teachers to evaluate student competency in real-world contexts. Assessment will be a dynamic piece of instruction, allowing students to integrate what they have learned and communicate this learning in an authentic way. The School considers ongoing assessment to be a daily necessity in providing teachers valuable information regarding student progress and instructional planning. Students will participate in performance tasks demonstrating real-world problem solving abilities. In addition, math journals and Thinking Maps provide insight into students’ cognitive processing of complex concepts. By reading these entries and engaging in conversations with students, teachers will be able to gauge current knowledge and perception of concepts and adjust instruction accordingly. This also provides teachers the opportunity to provide intervention instruction as needed.
