8th Grade Math Curriculum

In 8th grade math, students will build on their knowledge from Math Level H in 7th grade to complete Math Level I! 

This course bridges foundational math skills and high school algebra, deepening students’ understanding of equations, functions, geometry.

By the end of the year, students will be solving linear equations, working with irrational numbers, exploring systems and functions, and more. Interactive lessons, engaging activities, and real-world practice problems ensure students are prepared for Algebra 1 in high school.

You can find more math for eighth grade on YouTube at The Miacademy Learning Channel!

Before beginning math in 8th grade, students should have a solid understanding of seventh grade math concepts.

We suggest students take our seventh grade math course, Math Level H, or an equivalent course before starting Math Level I.

Your child is most likely ready to tackle eighth grade math if they can:

  1. Comfortably add, subtract, multiply, and divide multi-digit numbers, fractions, and decimals
  2. Understand and use ratios, rates (like miles per hour), and proportions in real-life situations
  3. Solve simple and multi-step math problems using equations and inequalities
  4. Use letters (like x or y) to stand for unknown numbers in equations
  5. Plot points on a graph to determine relationships
  6. Find the area of flat shapes and the surface area or volume of 3D shapes
  7. Work with positive and negative numbers and understand how they are related
  8. Easily convert between fractions, decimals, and percentages
  9. Use math rules, like the distributive property, to make problems easier to solve
  10. Read and summarize data from charts or surveys
  11. Interpret graphs and tables to understand how two sets of numbers are connected
  12. Recognize angles and understand the properties of shapes like triangles and rectangles

Each video lesson has printable math worksheets with additional activities to extend learning beyond the screen with a hands-on approach!

8th grade math standards focus heavily on pre-algebra topics, including functions, equations, and geometry knowledge, such as the Pythagorean Theorem. Students deepen their understanding of linear relationships, work with rational and irrational numbers, and explore real-world applications of math through data analysis, graphing, and volume calculations of three-dimensional shapes.

Common 8th grade math standards include: 

  • Recognizing the difference between rational and irrational numbers (like square roots or π) and how to estimate their value
  • Practicing using exponents and square roots in math problems
  • Using scientific notation for extremely large or small numbers
  • Solving one- and two-step equations and inequalities to find unknown values
  • Solving word problems with two equations at the same time (systems of linear equations)
  • Understanding what functions are and how they show relationships between numbers
  • Using functions to describe patterns, like tracking how something grows or changes
  • Exploring shapes to understand when they are the same size and shape (congruent) or just the same shape (similar)
  • Using the Pythagorean Theorem to find missing side lengths in right triangles
  • Calculating the volume of 3D shapes like cones, cylinders, and spheres
  • Creating and interpret scatter plots on a coordinate plane to look for patterns in data
  • Recognizing trends and relationships in sets of two connected data points

Standards can vary by state, so be sure to check what’s required where you live.

In this course, students will explore the essential building blocks of Algebra, including expressions, equations, and inequalities. They’ll practice simplifying expressions, solving for unknowns, and interpreting mathematical relationships using variables and real-world scenarios. Students will also gain experience working with coordinate graphs, analyzing patterns, and applying logic to solve increasingly complex problems. 

By the end of the course, students will be well-prepared for the challenges of Algebra 1 in ninth grade.
