An 8th-grade math program should cover various areas of mathematics, not just arithmetic. The primary strands for an 8th-grade math curriculum are number sense and operations, algebra, geometry, and spatial sense, measurement, and data analysis and probability.
What math are you supposed to do in 8th grade?
Linear equations and more equations — 8th grade is chock-full of algebra. Eighth grade math may seem like a separate language, or at least a parallel universe of definitions. When your child talks about things that are radicals, irrational and variable, chances are she’s referring to math class rather than reflecting on life.
What are the different types of math in 8th grade?

What math class should a 8th grader be in?
The average math for an 8th grader is 8th grade math which is prealgebra that is average. However some can be advanced and in Algebra or even Geometry. At some advanced middle schools, seventh graders take algebra and eight graders take geometry, usually. It all depends on your test scores, but that is normally the case.
What kind of math do you learn in 8th grade?
What Math Should an 8th Grader Know? An 8th grade math program should cover all the math strands, not just arithmetic. The major math strands for 8th grade curriculum are number sense and operations, algebra, geometry and spatial sense, measurement, and data analysis and probability.
Why do eighth graders take different math classes?
A major reason for this is that curriculum in the U.S. varies by state and often school district. Also, courses may vary not only by locality, but according to real or perceived math aptitude, as seen with tracking systems, Advanced Placement or remedial programs.
When did eighth grade math become common?
But beginning in the 1990s, these subjects -- or lead-in courses for them -- became more common in eighth grade classrooms across the country. This emergence of advanced classes at the eighth grade level was fueled in part by a desire for U.S. students, lagging in math compared to some of their first-world counterparts, to become more internationally competitive.
What is blended math?
Blended. Many schools offer courses fusing components of geometry, algebra and advanced arithmetic. These courses can go by many names, but are often just known as “eighth grade math.”. In addition to geometric, algebraic and pre-algebraic topics, blended courses often include units on number sense and operations, measurement, scientific notation, ...
Is geometry in 8th grade?
Geometry. In some districts students taking geometry in eighth grade may be very advanced -- having already completed Algebra 1 in seventh grade -- or the district may sequence courses in a less traditional order, resulting in Algebra 1 being taken in ninth grade. Although pre-geometry courses are quite rare, most students entering geometry have an ...
The Number System
Know that there are numbers that are not rational, and approximate them by rational numbers.
Geometry
Understand congruence and similarity using physical models, transparencies, or geometry software.
What is 8.EE.A.3?
8.EE.A.3 Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 x 10^8 and the population of the world as 7 x 10^9, and determine that the world population is more than 20 times larger.
What is the meaning of 8.F.B.5?
8.F.B.5 Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
What is the purpose of 8.SP.A.3?
8.SP.A.3 Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept. For example, in a linear model for a biology experiment, interpret a slope of 1.5 cm/hr as meaning that an additional hour of sunlight each day is associated with an additional 1.5 cm in mature plant height.
What is a function in math?
8.F.A.1 Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. (Function notation is not required in Grade 8.)
What is 8.NS.A.1?
8.NS.A Know that there are numbers that are not rational, and approximate them by rational numbers. 8.NS.A.1 Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which ...
