Grade 8 Math

Eighth grade math students will understand and use linear equations (like 100 + 40x) to solve problems. For example, compare the costs of two phone plans, each with a one time charge and a monthly fee. Understand and use functions: situations where one quantity depends on another, like when the distance a train travels depends on its speed. Explore and use the Pythagorean Theorem for right triangles (A2 + B2 = C2). For example, find the height of a ladder leaning against a wall. Create linear equations to model reallife data. For example, graph the height of a plant based on the hours of sunlight it gets.
By The End of Eighth Grade, Students Can:
 Explain the concept of irrational numbers.
 Use square and cube roots.
 Explain how proportions and linear equations are related.
 For example, explain the slope of a line as a unit rate.
 Solve single and paired linear equations.
 For example, if 3x + 5 = 11, then x = 2.
 Compare functions shown in different forms, like a table of values and a graph.
 Explain how angles inside and outside of a triangle are related.
 Explain how angles created by two parallel lines being cut by another line are related.
 Use formulas to solve realworld problems involving the volume of cylinders, cones, and spheres.
 Create a scatter plot of two related variables, like arm length and leg length.
