GRADE 8 MATH INSTRUCTIONAL FOCUS
According to the Missouri Learning Standards (MLS), eighth grade will focus on the following three critical areas:
 Formulating and reasoning about expressions and equations including modeling as association in bivariate data with a linear equation, solving linear equations and systems of linear equations.
 Understanding the concept of a function and using functions to describe relationships.
 Analyzing geometrical figures using distance, angle, similarity and congruence, and understanding the Pythagorean Theorem.

Know that there are numbers that are not rational, and approximate them by rational numbers

Work with radicals and integer exponents
Understand the connections between proportional relationships, lines, and linear equations Analyze and solve linear equations and pairs of simultaneous linear equations 
Define, evaluate, and compare functions
Use functions to model relationships between quantities 
Understand congruence and similarity using physical models, transparencies, or geometry software
Understand and apply the Pythagorean Theorem Solve realworld and mathematical problems involving volume of cylinders, cones and spheres 
Investigate patterns of association in bivariate data

Mathematical Practices

1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 
4. Model with mathematics.
5. Use appropriate tools strategically. 6. Attend to precision. 
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
