Grade 8 Pre-Algebra

In this unit, students will investigate translations, reflections, and rotations, and use these transformations to make informal arguments about congruence. They will also explore angle relationships on parallel lines and the triangle sum theorem.

In this unit, students will study dilations and similar figures. They will use similar triangles to explain, understand, and apply the concept of slope.

In this unit, students will make connections between proportional relationships and non-proportional linear relationships. They will compare representations of linear relationships and interpret them in context. Students also determine solutions to two-variable linear equations of different forms.

In this unit, students will solve linear equations and determine the number of possible solutions. They will also solve systems of two linear equations algebraically and graphically.

In this unit, students will learn about functions for the first time, analyze representations of functions, and examine functions in the context of the volume of cylinders, cones, and spheres.

In this unit, students will analyze data with two variables. They will use scatter plots and fitted lines to analyze numerical data and use two-way tables, bar graphs, and segmented bar graphs to analyze categorical data.

In this unit, students will develop fluency with expressions involving exponents, powers of 10, and scientific notation. They will also perform operations on numbers written in scientific notation.

In this unit, students will explore the Pythagorean theorem and different types of numbers (square roots and cube roots, rational and irrational numbers).
