Grade 9 Math in New Brunswick

Grade 9 is a turning point in math. Students in New Brunswick move from the foundational skills of middle school into more abstract topics like linear algebra, polynomial operations, and data analysis. StudyPug covers every topic in the NB Grade 9 math curriculum with clear video lessons and practice problems.

Powers and Exponent Rules

Students learn to represent repeated multiplication using powers and explore what happens when exponents equal zero. They then apply exponent rules to solve problems involving operations on powers. These skills are essential for algebra and higher-level math.

Rational Numbers and Order of Operations

Grade 9 students compare and order rational numbers and apply arithmetic operations to solve problems. They also apply order of operations to expressions that include both exponents and rational numbers, building accuracy and number sense.

Square Roots

Students identify and calculate square roots of perfect squares, then extend this to estimating and calculating approximate square roots of non-perfect squares. This prepares them for work with the Pythagorean theorem and geometry.

Linear Relations and Equations

A major focus of Grade 9 math is linear relations. Students create and verify linear equations from patterns, interpret graphs of linear relations, and solve various forms of linear equations in problem-solving contexts. They also solve and graph linear inequalities with rational coefficients.

Polynomials

Students identify and describe characteristics of polynomials, then add, subtract, multiply, and divide polynomials using concrete, pictorial, and symbolic methods. These skills form the foundation for Grade 10 and 11 algebra.

Geometry: Circles, Surface Area, Similarity, and Symmetry

The geometry strand covers properties of circles, surface area of composite 3D objects, similar polygons, scale diagrams of 2D shapes, and line and rotational symmetry. Students apply these concepts to solve real-world problems and justify their solutions.

Data Analysis and Probability

Students analyze how bias, language, ethics, cost, time, privacy, and culture affect data collection. They justify the use of population or sample, create and analyze histograms, plan and execute a complete data project, and analyze the role of probability in society.
