Academic standards list

Mathematics - Grade 8 — Mathematics

Introduction

Academic standards define the expectations for knowledge and skills that students are to learn in a subject by a certain age or at the end of a school grade level. This page contains a list of standards for a specific content area, grade level, and/or course. The list of standards may be structured using categories and sub-categories.

Mathematical Processes

 
Standard 1 — Mathematical Processes
 
Conceptual StrandThe Mathematical Process Standards are embedded in the content standards to reap the learning benefits gained from attention to them. These standards exemplify best teaching practices in mathematical instruction and mirror the NCTM Process Standards as well as the Common Core Mathematical Practices.Guiding QuestionWhat is the role of the mathematical processes standards in formative instruction?

Use scientific notation to compute products and quotients.
 
Solve real-world problems requiring scientific notation.
 

Algebra

 
Standard 3 — Algebra
 
Conceptual StrandThe Algebra Standard emphasizes relationships among quantities, including functions, patterns, ways of representing mathematical relationships, and the analysis of change.Guiding QuestionHow does algebra encompass the relationships among quantities, the use of symbols, the modeling of phenomena, and the mathematical study of change?
 
Grade Level Expectation

Identify, compare and contrast functions as linear or nonlinear.
 

Geometry and Measurement

 
Standard 4 — Geometry and Measurement
 
Conceptual StrandGeometry studies geometric shapes and structures and their characteristics and relationships. Understanding what a measurable attribute is and becoming familiar with the units and processes that are used in measuring attributes are the major emphasis of this standard.Guiding QuestionHow can students make and explore conjectures about geometry and reason carefully about geometric ideas while expanding their understanding of precision in measurement?
 
Grade Level Expectation

Understand the relationships among the angles formed by parallel lines cut by transversals.
Understand the necessary levels of accuracy and precision in measurement.
Understand both metric and customary units of measurement.
Use visualization to describe or identify intersections, cross-sections, and various views of geometric figures.
State Performance Indicator
Use the Pythagorean Theorem to solve contextual problems.
 
Apply the Pythagorean theorem to find distances between points in the coordinate plane to measure lengths and analyze polygons and polyhedra.
 
Find measures of the angles formed by parallel lines cut by a transversal.

Identify the intersection of two or more geometric figures in the plane.
 

Data, Probability and Statistics

 
Standard 5 — Data, Probability and Statistics
 
Conceptual StrandThe Data Analysis and Probability Standard recommends that students formulate questions that can be answered using data and addresses what is involved in gathering and using the data wisely. The basic concepts and applications of probability are also addressed, with an emphasis on the way that probability and statistics are related.Guiding QuestionHow do students experiences with the collection and analysis of data enable them to reason statistically and understand the various purposes of surveys, observational studies, and experiments?
 
Grade Level Expectation
