Grade 9 Math in Newfoundland and Labrador

Grade 9 math in Newfoundland and Labrador covers a wide range of topics that build on skills from earlier grades and prepare students for high school mathematics. StudyPug provides video lessons and practice problems for every topic in the NL Grade 9 math curriculum.

Numbers and Exponents

Students begin by developing an understanding of powers with integral bases and whole number exponents. They apply exponent laws, work with rational numbers, and practice the order of operations including exponents. These foundational skills are essential for success in algebra and higher-level math.

  • Powers with integral bases and whole number exponents
  • Exponent laws for integral bases
  • Rational numbers and operations
  • Order of operations including exponents
  • Square roots of perfect and non-perfect squares

Linear Relations and Equations

Grade 9 students explore linear equations and relations in depth. They generalize patterns using linear equations, graph linear relations, solve problems involving linear equations, and work with single-variable linear inequalities.

  • Generalizing patterns using linear equations
  • Graphing and analyzing linear relations
  • Solving problems with linear equations
  • Single-variable linear inequalities

Polynomials

Students develop an understanding of polynomials and model addition, subtraction, multiplication, and division of polynomial expressions using concrete, pictorial, and symbolic representations.

  • Understanding polynomials
  • Addition and subtraction of polynomials
  • Multiplication and division of polynomials by monomials

Geometry and Measurement

Geometry topics in Grade 9 include circle properties, surface area of composite 3-D objects, similarity of polygons, scale diagrams, and line and rotation symmetry.

  • Circle properties
  • Surface area of composite 3-D objects
  • Similarity of polygons
  • Scale diagrams of 2-D shapes
  • Line and rotation symmetry

Statistics and Probability

Students examine data collection methods, discuss the role of bias and ethics, choose between population and sample data, plan and carry out data projects, and explore the role of probability in society.

  • Bias, ethics, and data collection considerations
  • Population vs. sample data
  • Project-based data collection and analysis
  • Probability and its role in society
