- Performing operations with rational numbers: Emphasis is placed on adding, subtracting, multiplying, and dividing rational numbers, including fractions and decimals.
- Estimating square roots: Students explore the concept of square roots and learn how to estimate them for both perfect squares and non-perfect squares.
Expressions and Equations
Grade 8 math introduces students to more complex algebraic concepts. Key topics include:
- Solving linear equations and inequalities: Students learn to solve one-variable equations and inequalities, exploring methods such as graphing and using inverse operations.
- Understanding functions: The concept of a function is introduced, along with function notation, input-output tables, and graphs.
- Writing and analyzing expressions: Students practice writing algebraic expressions and learn to apply the distributive property and combine like terms.
Functions
Understanding functions is a critical component of the Grade 8 curriculum. Students will:
- Identify functions: Learn to distinguish between linear and nonlinear functions through tables, graphs, and equations.
- Analyze relationships: Explore how changes in one variable affect another, emphasizing proportional relationships and constant rates of change.
Geometry
The Geometry section of Grade 8 math incorporates various geometric concepts, including:
- Understanding congruence and similarity: Students explore the properties of geometric figures, learning the criteria for triangle congruence and similarity.
- Working with circles: Key concepts include understanding the relationship between radius, diameter, circumference, and area of circles.
- Analyzing geometric transformations: Students learn about translations, rotations, reflections, and dilations and how these transformations affect the properties of shapes.
Statistics and Probability
Statistics and probability are essential components of Grade 8 math that help students interpret data. Topics include:
- Collecting and analyzing data: Students learn to gather data, create graphs, and analyze statistical measures such as mean, median, mode, and range.
- Understanding probability: Students explore basic probability concepts, including experimental and theoretical probability, as well as the law of large numbers.
