Linear Algebra - 8th Grade Math Instructional Focus Units



In Linear Algebra, Grade 8 instructional focuses will be on: (1) Formulating and reasoning about expressions and equations, including modeling an association in bivariate data with a linear equation, and solving linear equations and systems of linear equations; (2) Grasping the concept of a function and using functions to describe quantitative relationships; (3) Using ideas about distance and angles, how they behave under translations, rotations, reflections, and dilations, and ideas about congruence and similarity to describe and analyze two-dimensional figures and to solve problems; and(4)?Understanding the statement of the Pythagorean Theorem and its converse and apply the Pythagorean Theorem to find distances between points on the coordinate plane, to find lengths, and to analyze polygons.UnitChapter(s)Main IdeaEstimated DaysMATHiaX Module1 1.1, 2, 3, 4Linear Equations and Functions40Linear Functions25, 6,Pythagorean Theorem18Right Triangles37, 8, 9Transformational Geometry23Geo Transformations410Line and Angle Relationships11Angle Relationships51.2-1.4, 11, 12Solving Linear Equations and Systems of Equations30Linear Equations & Systems of Linear Equations613Properties of Exponents14Exponents714Volume9Volume815, 16, 17Data Analysis25Bivariate DataEE/F = 57%NS/SP = 18%G = 25%HELPFUL LINKSAZ College and Career Ready Standards - Carnegie Course Content Map- Course 3 - Common Core Progressions – Use for explanations of standards sequencing, pointing out cognitive difficulties and pedagogical solutions, and providing further detail of mathematical content.
