Eighth Grade Math Concepts
Eighth grade math is a level where your students need to be proficient in certain math concepts. Eighth grade math concepts are very similar to those in seventh grade.
In middle school, students are expected to review all of their math abilities. The previous grade level concepts must be mastered.
Quantities
The students will not be introduced to any new number concepts, but they should feel comfortable in calculating multiples, square roots, integers, and factors. The student should have mastered these concepts by the time they reach eighth grade.
Dimensions
Students should have the ability to accurately use measurement terms at home as well as at school. Students should have the ability to solve complex problems, including those involving estimations in measurement and using formulas.
The students should have mastered the formulas to estimate and calculate area for trapezoids. Similar to this, students must be able calculate and estimate volumes of prisms. They should also know how to draw prisms according to the volume given.
The study of shapes and spatial relationships.
Students will be able draw, hypothesize and sketch geometric shapes, figures, and problems. They will also be able identify, sort and classify them, build and measure them, and then apply their knowledge. With dimensions provided, students should have the ability to draw and construct various shapes.
You will be able solve geometrical problems and have your students create them. Students should also be able identify and analyze shapes that have been translated, rotated or reflected. They can also describe congruent shapes. Also, students need to be able identify shapes that will tile or tessellate a plane.
Algebra and Patterning
In eighth-grade, students will begin to understand and explain patterns in more detail. Students should be able write simple algebraic formulas and equations.
Students should have the ability to evaluate simple linear expressions by using a single variable. Students should be confident in solving and simplifying algebraic equations by using four operations. They should also feel confident substituting natural numbers as variables in algebraic equations.
Chance
Probability is the measure of likelihood. It is used for everyday decision-making, in business, science, medicine and sports.
Your students should have the ability to create surveys, collect data that is more complex, organize it, and recognize and explain trends and patterns. Students should know how to label graphs correctly, and what makes one better than another. Students should know how to describe the data they have collected using terms such as mean, median, or mode.
Students should be able to make better predictions and understand how statistics can help them in decision-making and real-life situations. Students should be capable of making inferences and evaluating data based on their interpretations. Students should also be able to apply probability rules to games and sports.
