Middle School Mathematics Instructional Materials

In 2018, Seattle Public Schools adopted enVision Math as its core curricular material for middle school mathematics.  The current version in place is enVision+ Mathematics 2027 for middle school. 

  • Students are provided with a consumable textbook for use in class and/or at home  
  • Students can access enVision materials on the digital platform, SavvasRealize, through the SPS student portal (Clever)

Families can support learning at home using the enVision Family Resources for each topic and lesson.

Year at a Glance

Seattle’s middle school students transition from a focus on number systems in elementary school towards algebraic thinking, laying the foundation for high school course work.

Math 6 through Math 8 are aligned to the Washington State Standards that were adopted in 2012.  These courses are designed to address standards, or parts of standards, in a progression that builds conceptual understanding and connections between content.

In Math 6, students will build the concepts of ratio and rate and use them to solve problems. They will extend the number system to rational numbers and will write, use, and interpret numeric and algebraic expressions and equations. Finally, they will develop statistical thinking.

Topic 2 Integers and the Coordinate Plane
  • 15 Days, Quarter 1
  • Students extend what they know about whole numbers to work with integers and absolute value. Students apply their understanding of integers and rational numbers to graph points on the coordinate plane.
Topic 1 Positive Rational Numbers
  • 21 Days, Quarter 1
  • Students use algorithms to add, subtract, multiply, and divide fractions, mixed numbers, and decimals through thousandths. They use estimation to determine whether an answer is reasonable.
Topic 3 Numeric and Algebra Expressions
  • 21 Days, Quarter 1 – Quarter 2
  • Students work with numerical expressions that have more than one operation. They then extend that knowledge to work with algebraic expressions, which include at least one variable, or unknown quantity.
Topic 4 Equations and Inequalities
  • 23 Days, Quarter 2
  • Students learn that a problem situation can often be represented by an equation or an inequality that includes a variable. The equation or inequality can then be solved to find a solution to the problem situation.
Topic 5 Ratio and Rate

  • Students begin by using formulas to find the area of different polygons. They then progress to learning about nets, which are patterns for three-dimensional figures, and the surface areas of those figures. The topic ends with a lesson on volume.

In Math 7, students will focus on proportional relationships and develop understanding of operations with rational numbers. They will work with linear expressions and equations and with scale drawings and geometric constructions, and solve problems involving area, surface area, and volume. Finally, Math 7 students will draw inferences about populations based on samples.

Additional Courses Offered at the Middle School Level

An additional math class, taken concurrently with grade-level math, designed to support students in the core class through pre-teaching and focusing on math habits, growth mindset, and cultural and historical contributions to math.

There are four components of this course. First, pre-teach key content to position students to confidently engage in their core class. The Desmos curriculum is used to support pre-teaching, along with instructional strategies like number talks, problem strings, and rich tasks. Second, develop student’s habits of mind which blend mathematical mindsets with other research-based practices that support students learning mathematics. Third, teach students about growth mindset and how their brain grows. Fourth, engage students in learning about cultural contributions and history of mathematics, notable diverse mathematicians, and math in careers through the Humans Doing Math curriculum developed by Andrew McDonald. This course must be taught using the Math Empowerment curriculum materials. It is designed to include the four components mentioned above in a specific scope and sequence to support student engagement and learning. Teachers of Math Empowerment courses are required to attend the Math Empowerment Summer Institute and participate in the Math Empowerment Cohort throughout the year.
This is an additional math class, taken concurrently with grade-level math. Students may be in 6th, 7th, or 8th grade math courses. Math Empowerment sections are specific to grade level. For example, if a student is in Math 6, they would be enrolled in Math Empowerment with other 6th grade students who are also in Math 6. Students are recruited into the course, not placed. There should be communication with families and students prior to enrollment.

An additional math class, taken concurrently with grade-level math designed to support student success in core math content. This is an elective course.

The main components of this course are: Teach key content ahead of time to position students competently in core instruction​. Address learning gaps just-in-time to support access to core content. Provide further opportunities for students to deepen understanding and connections among mathematical ideas. Help students develop a growth mindset and self-efficacy.

Middle School Math Enrollment and Progressions

Students in Seattle Public Schools enroll into their next course in sequence for math. The charts below show different math course progressions a student might take during middle and high school starting with Math 6. 

Middle schools and K-8s offer courses that progress students through the standard progression of the math sequence. There may also be opportunities at the school to participate in a course progression that accelerates students in the sequence. These opportunities could include a compacting of concepts from multiple courses into one course or taking two math courses at the same time. Families should contact the middle school or K-8 to learn about the specific opportunities available at that school.

State and District Assessment Requirements

Students in grades 6 through 8 are required by the state to take the Smarter Balanced Assessment (SBA) in math. Students will take the math SBA corresponding to their grade level; so students in the 6th grade will be assessed on Math 6 standards, students in 7th grade will be assessed on Math 7 standards, and students in 8th grade will be assessed on Math 8 standards. For more information visit State of Washington Assessments Overview.

Seattle Public Schools requires two types of formative assessments during middle school. The first are curriculum embedded assessments (CEA) which are end of unit assessments provided in the enVision curriculum. The CEAs are administered three times a year, are tied to the course standards, and teachers can use CEA data to make adjustments to their instruction. The second formative assessment is Measures of Academic Progress (MAP). This assessment is administered twice a year. The MAP measures a student’s individual growth from fall to spring and from year to year. MAP data can be used for goal setting and identify math concepts that are strengths and area that may need additional support.
