Room: 323

Zero Period: C & D Days

Geometry Periods 3, 6a and 8b

Rm. 323

Geometry is the second year of the district’s traditional mathematics sequence. Geometry includes the logical study of plane and solid figures and the discovery of relationships of these figures through deductive and inductive reasoning.

Students will study the geometric plane using points and lines and then move through a rigorous triangle unit. Students will prove that triangles are congruent and two triangles are similar.

Following three-sided shapes, students will study the characteristics of quadrilaterals and polygons, as well as apply proportions and similarity theorems to similar polygons.

Finally, students will study 3-D planes using polygons to create polyhedra to calculate the surface area and volume of solid figures.

Algebra 1 w/ Ms. Moss- Periods 2,5a

Rm. 107

Algebra 1 is a foundational high school mathematics course that focuses on developing students’ skills in solving equations, analyzing functions, and applying algebraic reasoning to real-world problems. Throughout the course, students will explore a variety of topics, including simplifying expressions, solving linear equations and inequalities, graphing linear functions, and working with systems of equations. As the course progresses, students will delve into polynomials, factoring techniques, and quadratic functions, learning multiple methods to solve quadratic equations. Additional topics may include exponential functions, radical expressions, and basic data analysis. Emphasis is placed on problem solving, critical thinking, and mathematical communication, preparing students for success in higher-level math courses and everyday applications of algebra.
