Math Curriculum

Grade 8 Mathematics will move the students from the concepts developed in grades 6 and 7, modeling relationships with variables and equations and ratio and proportional reasoning, to making connections between proportional relationships, lines, and linear equations. The idea of a function introduced in grade 8 is a precursor to concepts about functions that are included in the high school standards.  Learning Units cover the following topics:

• Numbers & Operations
• 2D Geometry
• Equations with Roots & Radicals
• Pythagorean, Distance & Midpoints
• Scientific Notation
• Solving Equations
• Graphing Linear Equations
• Modeling Relationships
• Functions
• Data
• 3D Geometry

Students will have many opportunities to develop fluency, defined as speed and accuracy, with rational number arithmetic and solving multi‐step problems (including those involving positive and negative rational numbers and word problems leading to one variable equations) throughout the school year.  Students will continue to use ratios and proportional reasoning in multi‐step ratio and percent problems and extend their understanding of geometry concepts.  Learning units include the following topics:

• Numbers and Operations
• Expressions
• Equations & Inequalities
• Ratios & Proportions
• Percent
• Statistics & Probability
• Drawing Geometric Figures
• 2 D Geometry
• 3 D Geometry

Students will have many opportunities to build fluency in operations with multi-digit numbers including decimals to the thousanths place.  Students will build on their understanding of the number system from prior grades to extend to division of a fraction by a fraction, and apply them to proportional reasoning concepts.  Learning units will include the following:
• Numbers and Operations
• Factors and Multiples
• Fraction-Decimal Computation
• Ratios
• Percents
• Expressions
• Equations & Inequalities
• Applications of Equations
• Graphing
• Geometry
• Statistical Variability
• Data Displays

All math classes are 90 minutes long.  The NJCTL PMI math interactive program is utilized for the middle school grades.
