• ## Geometry (1st Period) The 8th-grade math Geometry program emphasizes abstract mathematical concepts and their applications. Students begin this course by mastering basic concepts such as points, lines, angles, and planes. Then they progress to explore the relationships among these concepts, such as parallel vs. perpendicular lines, congruence, similarity, and inequalities. Throughout the course, students learn to apply various postulates, theorems, and definitions to form proofs. The curriculum familiarizes students with all the geometric techniques necessary for higher-level mathematics. Successful completion of Geometry will allow students to begin high school with Algebra 2.

• # Unit 2: Reasoning and Proofs

Posted by Alexa Schmidt on 10/4/2019

In Geometry, students are learning one of the most important parts of Geometry: how to create a proof. We started with conditional statements and postulates, then move into paragraph proofs, algebraic proofs, and finally geometric proofs. We work together as a class, in pairs, and finally individually as students build up their skills and confidence with proof writing.

To extend at home, discuss the importance of being able to create a sound and logical argument supported by evidence. What value does this skill have in our society today? The students in the above image have worked together to create two-column proofs. We worked on these "drag and drop" proofs before creating our own proofs from scratch.

• # Unit 1: Tools of Geometry

Posted by Alexa Schmidt on 9/16/2019

Currently, in school, the students are learning the fundamental tools of Geometry: points, lines, planes, and angles. We are discussing how to define (if possible) these terms, how to measure them, and how they relate to each other.

To extend at home, ask your child where to find each of these examples in a room of your home:

• Collinear points
• Noncoplanar lines
• The intersection of two planes
• Supplementary angles
