8th grade Math

Eighth-grade math is the bridge to algebra: real numbers and scientific notation, slope and linear relationships, functions, transformations and dilations, the Pythagorean theorem, volumes of cylinders, cones, and spheres, equations with variables on both sides, scatterplots and trend lines, and the real cost of credit and the power of saving early.

Practice activities

🎈Balloon Pop: Real NumbersSort rational from irrational numbers and match scientific notation.
🔁Real Numbers, Dilations, and TransformationsSets of real numbers, approximating irrationals, scientific notation, ordering, similar shapes and dilations on the coordinate plane, and the four transformations.
📈Slope, Lines, and FunctionsSlope from similar triangles, proportional graphs and unit rate, rate of change and y-intercept from tables and graphs, y = kx vs. y = mx + b, trend lines, direct variation, and identifying functions.
📏Cylinders, Cones, Spheres, and the Pythagorean TheoremVolume of cylinders, cones, and spheres, lateral and total surface area, the Pythagorean theorem and its converse, distance on the coordinate plane, and angle facts for triangles and parallel lines.
🏦Equations, Data, and the Cost of CreditEquations with variables on both sides, scatterplots and association, mean absolute deviation, random samples, loans and interest, investing early, payment methods, financial responsibility, and saving for college.
⚖️Balance Scale: Both SidesEquations with x on both sides of the scale.
💳What Borrowing CostsReal credit card and car-loan rates from U.S. banks: scatterplots of rate by year, how the rate and the length of a loan change what it costs, and the total cost of paying off a card. Real data from FRED, Federal Reserve Bank of St. Louis.
🏦Corner Store: Savings and InterestFind simple interest on savings, and compare it with interest compounded yearly.

How to help at home

Let your child handle real numbers: a restaurant bill, a discount, miles per gallon.
When they are stuck, ask what the question is asking before touching the numbers.
Celebrate the strategy, not just the answer: what did you try first?
