# The Math Classroom

As part of OUSD’s strategy to prepare students for college, career, and community and provide the mathematical foundation required for admission to a UC or CSU school, we’ve revised all secondary mathematics courses to be more rigorous and to:

• spend more time diving more deeply conceptually into the most important mathematic principles
• emphasize critical thinking, collaboration, practical application, and problem solving
• create greater student engagement that produces a deeper understanding more readily applied to novel problems or contexts

To learn more about the OUSD board-approved math course pathways and what math courses your student can take (including the pathway for students who are ready for algebra in the 8th grade and the pathway for students who need extra help to be successful), view the OUSD Middle School Mathematics Parent Newsletter.

## Math 6: Proportional Relationships

6th graders are working on understanding the concepts of ratio and unit rate.  They are using ratio and rate reasoning to solve real-world and mathematical problems, including unit pricing, constant speed, percent of a quantity, and unit conversions.  They will use multiple representations (ratio tables, tape diagrams, double number lines, equations, line graphs,  ect.) to solve problems and explain their thinking.  In this unit, multiplication and division are used to make equivalent ratios, and multiple representations will be used to conceptualize and visualize relative sizes of quantities.

Supporting Math (Previous math concepts used in this unit)

• Equivalent Fractions
• Multiply Fractions
• Use variables
• Look for patterns
• Use tables

## Math 7:  Operations on Rational Numbers

7th graders are working on operations with positive and negative rational numbers.  They will apply and extend previous understanding of operations with fractions to add, subtract, multiply, and divide positive and negative rational numbers (fractions, decimal,integers)  to solve real-work problems.

Supporting   Math (Previous Math Concepts Used in this Unit)

• Use positive and negative to represent quantities in real-world
• Represent points on four quadrant coordinate plane
• Order absolute value of rational numbers
• Add, subtract, multiply, divide positive rational numbers  (decimals, fractions, integers)

## Math 8: Linear Relationships

8th graders are working on linear and proportional functions.  They will work on understanding that the slope between any two points is the same on a non-vertical line.   Similar triangles will be use to deepen their  understanding of the meaning of slope.  Students will define, evaluate, and compare linear functions. They will also use the functions to model relationships between quantities.

Note: If your student is in Mr. Corwin’s class, you’ll find homework assignment and document on his website www.classjump.com/corwin.
