Mathematics

The mission of the Rivers mathematics department is to inspire curiosity and foster enthusiasm for learning and applying mathematics. Through meaningful work and student-centered classrooms, we create an environment that encourages students to collaborate with their peers and teachers while also taking ownership of their own learning process. We aim for students to feel both challenged and successful by pushing them outside their comfort zones, but always instilling in them a confidence that they have the tools to tackle complex and unfamiliar problems. They learn to think creatively and develop critical thinking skills that allow them to approach any problem like a mathematician. We believe this way of teaching and learning leads to self-assured students who will leave with an appreciation for and excitement of the study of mathematics.
  • Pre-Algebra, Grade 6

    The Pre-Algebra 6 course begins students’ formal preparation for algebra. The program helps students gain mastery of computation and estimation through various small-group problem-solving activities and independent skills practice. The course develops students’ thinking in the key mathematical processes of counting, visualizing, comparing, estimating, measuring, modeling, reasoning, connecting, representing, and using tools. Among the topics covered are factors, multiples, fractions, decimals, percents, ratios, proportions, Cartesian coordinates, area, perimeter, volume, and data analysis. Emphasis is placed on real-life applications, often involving multiple-step word problems that require students to apply what they have learned to new situations. During the year, the Pre-Algebra 6 course is integrated with the sixth-grade science (Earth Science) and Humanities (The World and Water) courses through projects.
  • Pre-Algebra, Grade 7

    This course continues students’ preparation for algebra and is designed to address four main topics: number theory, statistics, geometry, and basic algebra skills. In number theory, students explore the number system through the use of patterns, fractions, decimals, and percents. The statistics unit examines probability, data collection, data presentation, and decision-making, and the geometry unit investigates properties and patterns of geometric shapes and theories. Students are also exposed to methods and skills of manipulating symbolic representations. This course uses activities, labs, games, and projects to help students comprehend and master the concepts covered.
  • Math, Grade 8

    This course builds a strong foundation in Algebra I. Students explore various topics including sequences, exponent laws, linear and exponential functions, and equation-solving strategies that include inequalities and systems. They analyze quadratic functions through graphing, factoring, and solving equations. Additional topics include polynomial operations and features of functions. 

    The course is designed to support students in developing their foundational mathematical skills needed for success in algebra. Emphasizing real-world applications and critical thinking, this course also helps students develop mathematical fluency through direct instruction and practice throughout each unit.

  • Math, Grade 8 - Accelerated

    This course covers the same topics as Math, Grade 8 at an accelerated pace to allow for more depth, complexity , and extension problems. The course encourages exploration and critical thinking through discovery-based learning with support from direct instruction to strengthen understanding.
  • Math, Grade 8 - Extensions

    This course covers the same topics as  Math, Grade 8 - Accelerated.  This extensions-focused course engages students in active, discovery-based learning to promote critical thinking and problem-solving, supported by focused direct instruction to ensure mastery of challenging concepts. Emphasis will be placed on building a set of tools to solve challenging problems independently and creatively through independent and collaborative work.
