Texas STAAR Algebra 1 Free Worksheets: 59 Printable TEKS-Aligned Algebra 1 PDFs with Answer Keys
Algebra I in Texas sits unusually high on the high school calendar. It is the first STAAR end-of-course exam a student sits in mathematics, it is required for graduation under state law, and a substantial percentage of ninth graders meet both the math and the test for the first time in the same fall. That setup pushes a lot of families into a search for the right kind of practice. Not more pages. Not harder pages. The right pages — specific enough to learn one thing from at a time, and short enough that a tired teenager will actually finish them.
Texas Algebra I classrooms run from a Houston high school across a vast attendance zone to a small district outside Austin, from the campuses dotting the corridors between Dallas and Fort Worth to a school near the river in San Antonio, from an El Paso building within sight of two countries to anywhere else in the state. The TEKS — the Texas Essential Knowledge and Skills for Algebra I — are the same in all of those rooms, and so is the STAAR End-of-Course Assessment that closes the course in the spring. What changes between students is how much practice they have had with the specific skills the test names.
Fifty-nine PDFs. Each one skill. Each aligned to a TEKS strand.
What’s on this page
Fifty-nine single-skill PDFs aligned to the Texas Essential Knowledge and Skills for Algebra I. The set follows the TEKS strands a Texas classroom actually moves through: linear functions, equations, and inequalities in one variable; systems of two linear equations and inequalities; quadratic functions and equations; exponential functions and equations; and the number and algebraic methods that support all of them — exponents, radicals, polynomials, and factoring. Each PDF stays inside one TEKS skill, so a sitting on “Writing the Equation of a Line” does not also test factoring, and a sitting on “Solving Quadratics by the Quadratic Formula” does not pull in exponent rules.
Every PDF begins with a one-page Quick Review. The skill is stated in plain English, with one fully worked example whose reasoning is visible at each step, plus a short note flagging the misstep students most often make. Then twelve practice problems sequenced from a gentle opening to the level of difficulty STAAR Algebra I tends to reach — including the kind of process-skills items the test is known for, where the work is less about computing and more about interpreting. The final page is a student-facing answer key written in a patient, tutoring tone, short enough to read in a minute and complete enough to teach a fifteen-year-old something real about whatever they missed.
Foundations of Algebra
This chapter lays the groundwork, moving from numbers to letters and putting properties and order-of-operations to work on real problems. These worksheets give Texas students focused, low-pressure practice.
- Variables, Expressions, and Properties
- Order of Operations and Evaluating Expressions
- Simplifying Algebraic Expressions
- Introduction to Equations and Solutions
- Personal Financial Literacy
Solving Linear Equations
Now the central skill of the course: isolating a variable, from one clean step through multi-step solves and rearranging formulas. For Texas students, fluency here shows up directly on the STAAR.
- Solving One-Step Equations
- Solving Two-Step Equations
- Solving Multi-Step Equations
- Equations with Variables on Both Sides
Inequalities and Absolute Value
Here a single answer becomes a set: solving and graphing inequalities, handling the sign-flip rule, and unpacking absolute value. Getting comfortable here pays off all the way through the STAAR.
- Solving One-Step Inequalities
- Solving Multi-Step Inequalities
- Compound Inequalities
- Absolute Value Equations
Relations, Functions, and Sequences
This unit introduces function thinking: notation, inputs and outputs, and the patterns that arithmetic and geometric sequences follow. Time spent here is time saved when the STAAR rolls around.
- Function Notation and Evaluating Functions
- Domain and Range
- Graphing Functions and Transformations
- Piecewise Functions
- Combining Functions
- Inverse Functions
Linear Functions and Their Graphs
Linear graphs take focus: slope, intercepts, point-slope and slope-intercept forms, and special line relationships. Across Texas, this is one of the skills that rewards regular reps.
- Slope-Intercept Form
- Point-Slope Form
- Standard Form of a Linear Equation
- Writing Linear Equations from Graphs and Tables
- Parallel and Perpendicular Lines
- Inverse Variation
Systems of Equations and Inequalities
Here several equations are solved together, and systems of inequalities mark out whole regions of valid solutions. It is worth the extra reps for Texas learners aiming for a strong score on the STAAR.
- Solving Systems by Graphing
- Solving Systems by Substitution
- Solving Systems by Elimination
- Applications of Systems of Equations
- Systems of Linear Inequalities
- Solving Linear-Quadratic Systems
Exponents, Polynomials, and Real Numbers
The algebra of powers and polynomials: exponent rules, adding and multiplying polynomials, special products, and real numbers. Houston families can use these pages to lock the skill in before it’s tested.
Factoring
Students learn to rewrite polynomials as products: greatest common factor, trinomial factoring, and recognizable special forms. In Houston classrooms it tends to separate confident students from hesitant ones.
- Greatest Common Factor and GCF Factoring
- Factoring Trinomials: \(x^2 + bx + c\)
- Factoring Trinomials: \(ax^2 + bx + c\)
- Factoring Special Products
Quadratic Functions and Equations
The chapter covers parabolas and three solution paths for quadratics, plus what the discriminant reveals. Steady practice now makes the STAAR feel far more manageable later.
- Graphing Quadratic Functions
- Characteristics of Quadratic Functions
- Solving Quadratics by Factoring
- Solving Quadratics by Completing the Square
- Solving Quadratics by Square Roots
- The Discriminant
- The Quadratic Formula
- Quadratic Applications and Modeling
Statistics and Probability
Data analysis and probability close out the core, from box plots and histograms to counting principles. Master it early and the rest of the Texas course leans on it with ease.
- Measures of Center and Spread
- Scatter Plots and Correlation
- Lines of Best Fit and Predictions
- Two-Way Frequency Tables
Exponential Functions and Modeling
Here change compounds: exponential growth and decay, their graphs, and comparisons among model families. It’s a frequent early hurdle for learners in Houston and across the state.
More Topics
- Absolute Value Inequalities
- Direct Variation
- Displaying Data with Box Plots
- Displaying Data with Histograms
- Exponential Decay
- Graphing Cube Root Functions
- Graphing Square Root Functions
How to use these worksheets at home
The most reliable way to get a Texas Algebra I student moving is to print pairs of related sheets across the same week. The TEKS are deliberately layered, and pairing the layers makes the structure visible. Print “Solving Two-Step Equations” early in the week and “Solving Multi-Step Equations” a day or two after; the second sheet is the first with one more move. Schedule “Slope and Rate of Change” right before “Slope-Intercept Form,” and the slope a student just computed walks directly into the m of y = mx + b. Set “Factoring Trinomials” the evening before “Solving Quadratics by Factoring,” and the second worksheet feels like the natural finishing move of the first.
Keep the sittings short. Two afternoons a week, fifteen to twenty unbothered minutes each, is enough to move a Texas student through the full set by the time the spring STAAR window opens. Algebra consolidates between sessions more than during them, so the days off are doing work too. Print one PDF, set it on the table, and step away. A teenager in Houston or San Antonio or El Paso will do their most honest math when allowed to work alone, and the dignity of finishing a page solo is part of what makes the skill stick.
The answer key belongs at the end of every session — never the beginning. Hand it over after the work is done, let your student grade themselves, and use the moment to talk through any miss. A short, calm conversation about a single problem is worth far more than a long lecture about a whole topic.
A note about STAAR Algebra I
The STAAR Algebra I End-of-Course Assessment is administered in the spring of the year a student completes the course, with retake opportunities later. Under Texas law, the Algebra I EOC is one of the STAAR exams a student must address to graduate, which is why families often plan its run-up months in advance. The exam is built directly on the TEKS for Algebra I — the same standards these worksheets are aligned to — and it covers the full arc: linear equations, inequalities, and functions; systems; quadratics; exponentials; and the supporting algebraic methods. STAAR Algebra I uses a mix of multiple-choice items, technology-enhanced items, and short constructed-response problems, with a strong emphasis on the process skills the TEKS call out by name — analyzing, modeling, justifying, and communicating mathematical reasoning.
Because each PDF here is mapped to a single TEKS strand, the set lets you treat the spring as a checklist rather than a wall. Print a sheet, see how it goes, and let one piece of evidence decide what to print next. A clean page is permission to move on; a stumble points to the prerequisite that needs another sitting. That is a far faster route to readiness than re-reading a textbook cover to cover.
A short closing
The Texas STAAR Algebra I EOC is a long test, and the quietest way to feel ready for it is to make the work on the test look familiar. Bookmark this page, print one PDF tonight, and let your Texas student begin with the smallest, friendliest TEKS skill on the list. By the time spring arrives, the page on the test screen will look very much like the page that has been on your kitchen table — and that resemblance is the whole point of a careful year.
