• 8th 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 real-life 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 real-world problems involving the volume of cylinders, cones, and spheres.
• Create a scatter plot of two related variables, like arm length and leg length.
