STAAR Math Reference Sheet & Formula Chart
Master every formula, geometric relationship, and unit conversion on the Texas STAAR assessment. Includes complete reference charts for Algebra 1 and Grades 3 through 8 aligned directly with state TEKS standards.
STAAR Formula Chart Algebra 1
Official Texas Essential Knowledge and Skills (TEKS) mathematics reference formulas for High School Algebra 1 EOC.
Graphing calculator (handheld TI-84/Nspire or integrated Desmos) is required for all students throughout the entire Algebra 1 EOC assessment.
Linear Forms & Slope Formulas
Standard, slope-intercept, point-slope equations, and rate of change
Where m is the rate of change (slope) and b is the y-intercept (0, b).
Where A, B, and C are integers with A ≥ 0, and A and B are not both zero.
Where m is slope and (x₁, y₁) is any known coordinate on the line.
Ratio of vertical change to horizontal change between coordinates (x₁, y₁) and (x₂, y₂).
Where k represents the constant of variation (passing through origin).
Quadratic Equations & Functions
Standard, vertex forms, quadratic formula, and axis of symmetry
Where a ≠ 0, c is the y-intercept, and the parabola opens upward if a > 0.
Where (h, k) represents the vertex coordinates (maximum or minimum point).
Calculates the real and complex roots (zeros/x-intercepts) when ax² + bx + c = 0.
Vertical line that divides a parabola into two symmetric halves.
Exponential Functions
Growth, decay, and geometric sequences
Where a is the initial value (y-intercept at x = 0) and b is the growth/decay factor (b > 0, b ≠ 1).
Where a is starting amount, r is decimal percentage rate, and t is time.
Laws of Exponents & Radicals
Multiplication, division, and power rules for algebraic expressions
Add exponents when multiplying terms with matching bases.
Subtract exponents when dividing terms with matching bases (a ≠ 0).
Multiply powers when raising an exponential expression to another power.
A negative exponent denotes the reciprocal of the positive power (a ≠ 0).
The denominator n is the root index; the numerator m is the power.
Any non-zero real number raised to the zero power equals 1.

Understanding the Texas STAAR® Mathematics Reference Materials
The Texas Education Agency (TEA) embeds an official Mathematics Reference Materials sheet in every online and paper-based STAAR assessment. Knowing how to efficiently navigate these formulas gives Texas students a decisive speed and accuracy advantage.
STAAR Formula Chart Algebra 1Take Algebra 1 Quiz
The algebra 1 staar formula chart supplies indispensable formulas for linear, quadratic, and exponential relationships. High school students preparing for the Texas End-of-Course (EOC) exam must master the standard slope-intercept equation (y = mx + b), point-slope form, the quadratic formula (x = (-b ± √(b² - 4ac)) / (2a)), and foundational exponent laws. Practicing with our interactive tests helps students recognize when to apply these formulas under exam conditions.
8th Grade STAAR Math Reference Sheet & Formula ChartTake Grade 8 Quiz
The 8th grade staar math reference sheet focuses heavily on 3D geometry and the Pythagorean theorem (a² + b² = c²). Students must compute the volume of cylinders, cones, and spheres, as well as differentiate between lateral surface area (S = Ph) and total surface area (S = Ph + 2B). Additionally, financial literacy standards test both simple interest (I = Prt) and compound interest (A = P(1 + r)ᵗ).
7th Grade STAAR Math Reference SheetTake Grade 7 Quiz
On the 7th grade staar math reference sheet, proportional reasoning (y = kx) and circle geometry take center stage. Students receive standard formulas for the circumference (C = 2πr) and area of a circle (A = πr²), volume of prisms and pyramids, along with customary and metric conversion tables.
6th Grade STAAR Math Reference SheetTake Grade 6 Quiz
The 6th grade staar math reference sheet provides 2D geometric area equations for triangles, rectangles, parallelograms, and trapezoids, as well as the volume of rectangular prisms (V = Bh). It also includes conversion charts for customary and metric systems that students use to solve multi-step unit conversion word problems.
5th Grade STAAR Math Reference SheetTake Grade 5 Quiz
The 5th grade staar math reference sheet details perimeter, area, and volume models alongside comprehensive measurement conversion tables. In 5th grade, understanding how to convert between miles, yards, feet, and inches, or liters and milliliters, is an essential readiness standard tested with complex real-world situations.
4th Grade & 3rd Grade STAAR Math Reference MaterialsTake Grade 4 Quiz
Elementary Texas testing introduces foundational reference charts covering perimeter of squares and rectangles, area calculations, and standard unit equivalents. Practicing early ensures students build testing confidence and avoid simple conversion mistakes on the official spring test.
