Eighth grade children are taught by using a combination of interactive activities, learning games, printable worksheets, assessments, and reinforcement. Manipulative are very important for eighth grade math lessons. The significance of eighth grade math is taught by using many tools and using the major math strands for eighth grade curriculum which are number sense and operations, algebra, geometry and spatial sense, measurement, and data analysis and probability.
These are all critical lessons for an eighth grade math curriculum. Eighth grade math students build on what they learned in kindergarten through seventh grade math. In eighth grade math they work with positive and negative numbers, exponents, and the order of operations, as well as scientific and standard notation.
They learn more about working with whole numbers, fractions, mixed numbers, decimals, and integers. There are more in depth lessons in measurement, geometry, algebra, data analysis and probability. Eighth grade will prove to be a very challenging year for most students because they will be taught many new and difficult concepts. Eighth grade will teach student's word names and standard numerals for integers, fractions, decimals, numbers expressed as percents, numbers with exponents, numbers expressed in scientific notation, absolute value, radicals, and ratios.
Students now have a full picture of the real number system. Lastly, in Unit 8, Bivariate Data , students analyze data in two variables using linear equations and two-way tables. They use these structures to make sense of the data and to make justifiable predictions.
Students learn to simplify complex-looking exponential expressions, and they learn efficient ways to describe, communicate, and operate with very large and very small numbers. Students hone their skills of solving multi-step equations and inequalities, redefining their definition of "solution" to include cases such as infinite solutions, and interpreting solutions in context.
Students investigate congruence and similarity by studying transformations of figures in the coordinate plane, and apply these transformations to discover new angle relationships.
Students learn how to represent, interpret, and analyze functions in various forms, leading to understanding features such as rates of change, initial values, and intervals of increase and decrease. Students compare proportional relationships, define and identify slope from various representations, graph linear equations in the coordinate plane, and write equations for linear relationships.
Students explore what happens when you consider two linear equations simultaneously, and explore the many rich applications that can be modeled with systems of linear equations in two variables.
Students learn about irrational numbers, approximating square roots of non-perfect square numbers, and investigate the well-known Pythagorean Theorem to solve for missing measures in right triangles. Students combine their knowledge of linear functions with knowledge of data representations and analysis to make the jump from univariate data in one variable to bivariate data in two variables.

In eighth grade students are just starting to compare different data sets and learn what conclusions they can draw from them. Specifically, eighth graders should be able to analyze data using charts and graphs and be able to explain the patterns in the data.
Are kids who date more or less likely to do chores? Eighth grade math is hugely important for the big kahuna math to come in high school. And if you have trouble with this stuff, remember the best way to learn stuff is often to teach it, so ask your child to give you a lesson in eighth grade math. Preschooler math — teach them shapes and spatial skills. Could early math skills matter more than early reading skills? Please enter a valid email address.
Thank you for signing up! Server Issue: Please try again later. Sorry for the inconvenience. Your 8th grader and math under Common Core Standards Linear equations and more equations — 8th grade is chock-full of algebra. By the end of eighth grade, your child will be close to mastering these skills: Understanding irrational numbers and comparing them to rational numbers. Using linear equations, linear functions and systems of linear equations to explain relationships between two variables or values.
Creating graphs and other diagrams to illustrate those relationships. Understanding the concept of a function as one quantity or value changing another quantity or value. Computing square roots and their opposite, exponents. Determining if shapes are identical by rotating them, flipping them, and moving them around on a graph.
Applying the Pythagorean Theorem to find unknown lengths in right triangles and explaining why it works.
