Math 8

Big Ideas in 8th grade include:

• Studying and applying transformational geometry: rigid, congruence, dilations, and similarity
• Expanding and applying their understanding of proportional reasoning and relationships
• Expressing linear relationships using equations, tables, and graphs, and making connections across these representations. 
• Identifying characteristics of functions by looking at a table, graph, equation, or word problem.
• Identifying characteristics of linear and nonlinear relationships by looking at a graph, table, equation, or word problem
• Expanding their ability to work with linear equations in one and two variables. 
• linear modeling, inequalities
• Exploring,graphing, and solving absolute value equations
• Explorating, graphing, and solving inequalities
• Extending the definition of exponents to include all integers, and in the process codifying the properties of exponents. 
• Writing and solving systems of equations
• Developing and applying their knowledge of scientific notation
• Developing and applying their knowledge of Pythagorean Theorem
• Exploring and graphing nonlinear functions such as quadratic and piecewise functions

The mathematical work for Grade 8 is broken into 9 units. Students in the advanced sections have a hybrid curriculum based on the Illustrative Math 8th grade curriculum and the Phillips Exeter Academy Math 1 Algebra/Geometry curriculum.

1. Rigid Transformations and Congruence
2. Similarity, Dilation, and Slope
3. Linear Relationships
4. Linear Equations and Systems
5. Functions and Volume
6. Associations in Data
7. Exponents and Scientific Notation
8. Pythagorean Theorem
9. Putting It All Together
