A full year on algebra alone, from variables and integers through quadratics, in 180 daily lessons.
About this course
This is a dedicated Algebra I course that spends the entire year on algebra and nothing else. It opens with the language of algebra — variables, terms, coefficients, order of operations, and the properties of real numbers — then covers integers and rational numbers on the number line, one-step through multi-step equations, equations with variables on both sides, literal equations solved for a chosen variable, and inequalities of every kind including compound and absolute value. Functions come next: domain and range, function notation, the vertical line test, direct variation, rate of change, slope, and the slope-intercept, point-slope, and standard forms of a line, along with parallel and perpendicular slopes, scatter plots and lines of best fit, and word problems on distance, mixture, age, and simple interest. The second half of the year covers systems solved by graphing, substitution, and elimination; exponent rules, scientific notation, and exponential growth and decay; polynomials, FOIL, and special products; a full unit on factoring that runs through grouping, trinomials with a leading coefficient, differences of squares, and the sum and difference of cubes; rational expressions and equations with attention to extraneous solutions; radicals, the Pythagorean theorem, and the distance and midpoint formulas; quadratic functions solved by graphing, square roots, completing the square, and the quadratic formula; and a closing statistics unit with box plots, histograms, correlation, probability, permutations, and combinations.
The course is 180 lessons in 15 units of 12, one lesson per school day at about 55 minutes, which is a full year. A lesson opens with prayer, states the day's idea in a short paragraph, defines the key vocabulary, and moves quickly into three to five fully worked examples with every step shown. A brief real-world application and a KJV verse tied to the day's math follow, along with the same closing notes on study habits and common mistakes that appear in every lesson. The instruction is compact and the worked examples carry most of the teaching, so a student who needs an idea explained several different ways will do better with you sitting nearby than working alone. Every lesson ends with a ten-question multiple-choice quiz that grades itself, and every unit closes with a review lesson. The final unit is cumulative review plus a few application lessons on algebra in science, finance, and geometry. Materials are pencil, graph paper, a Bible, and an optional calculator.
Algebra itself is taught from the ground up, so no prior algebra is needed, but your student does need a settled pre-algebra foundation: confident arithmetic with fractions, decimals, and percents, comfort with negative numbers, and familiarity with exponents, square roots, and the coordinate plane. Freedom Homeschool also offers a general Math course at ninth grade, and the two overlap heavily. That course is an integrated survey — algebra, proof-based geometry, and statistics through z-scores in the same year. This course sets the geometry aside and spends the year on algebra alone, which lets it go considerably deeper on functions, polynomials, factoring, rational expressions, and radicals. Each is a full 180-lesson year on its own, so assigning both would mean two math courses running at once. Most families will pick one: the general Math course for a broad year, or this one for a student who needs a full Algebra I on the transcript before moving on to Geometry.

One whole lesson, exactly as it comes
This is a real lesson taken from the middle of the course — the teaching text, the practice, the homework, and the first three quiz questions with their answers. It is not a marketing excerpt.

Complete the worked examples and practice problems
Connect lesson content with biblical worldview
Multiplying and Dividing in Scientific Notation
Multiply: multiply the a's, add the exponents. Divide: divide the a's, subtract exponents. Adjust to keep 1 <= |a| < 10.
Key Vocabulary
Multiply: a's multiply, exponents add
Divide: a's divide, exponents subtract
Worked Examples
Example 1: (210^3)(310^4) = 6 * 10^7.
Example 2: (410^5)(210^-2) = 8 * 10^3.
Example 3: (610^8)/(310^2) = 2 * 10^6.
Example 4: (510^4)(410^3) = 2010^7 = 210^8.
Real-World Application
Astronomers compute distances/times across the universe in scientific notation.
Christian Worldview Connection
Psalm 8:4 — what is man? In a universe of 10^80 atoms, God is mindful of us.
Study Tips
Math is best learned actively. Work each example yourself with pencil and paper before peeking at the solution. After completing the practice, redo any problems you missed without looking. Repetition cements the concept into memory.
Try teaching today's idea aloud to a parent or sibling. If you can explain it clearly, you understand it. If you stumble, that pinpoints what to review.
Common Mistakes to Avoid
Watch your signs carefully — a missed negative is the most common error in algebra. Always show your work in clear, ordered steps so you can find your own slips. When checking an answer, plug it back into the ORIGINAL equation, not into a step you derived along the way.
Looking Ahead
Today's skill will be used in tomorrow's lesson and throughout this entire unit. Algebra builds in chains: weakness in one link breaks the next. Master today's idea before moving on. With prayer, persistence, and practice you will succeed in honoring God with the mind He has given you.
