Read the post →High school FAQ
What math do high school students take?
Most US high schools teach math as Algebra 1, Geometry and Algebra 2, often followed by precalculus, statistics or calculus. Some states use an integrated pathway (Math 1, 2 and 3) that mixes the same content each year. Many students take Algebra 1 in 9th grade, though some start it in 8th grade.
How are the high school Common Core math standards organized?
Instead of grade levels, the high school standards are grouped into conceptual categories: Number and Quantity, Algebra, Functions, Modeling, Geometry, and Statistics and Probability. A code such as HSA-REI.B.3 means High School, Algebra, Reasoning with Equations and Inequalities, cluster B, standard 3, which is solving linear equations in one variable.
What is taught in Algebra 1?
Algebra 1 covers solving linear equations and inequalities, rearranging formulas, graphing linear functions and finding slope, solving systems of linear equations, working with exponents and polynomials, factoring, and solving quadratic equations. Most courses also include some statistics, such as reading histograms and box plots and comparing data sets.
How do you solve a quadratic equation by factoring?
Write the equation in standard form so one side equals zero, factor the quadratic expression, then set each factor equal to zero and solve. For example, x² − 5x + 6 = 0 factors to (x − 2)(x − 3) = 0, so x = 2 or x = 3. This uses the zero product property and is part of standard HSA-REI.B.4b.
Is the Pythagorean theorem taught in middle school or high school?
Students first learn and apply the Pythagorean theorem in 8th grade (8.G.B.7). High school geometry builds on it with right triangle trigonometry, using sine, cosine and tangent together with the Pythagorean theorem to solve right triangles in real-world problems (HSG-SRT.C.8).
What subjects do you have for high school?
Math is the biggest set, with cases for every core standard listed above. There are also science activities in the same detective format: students solve each question, match the answer to a suspect and cross suspects off until one is left.
