Texas STAAR Algebra I
The five STAAR Algebra I reporting categories, from algebraic methods to exponential functions. (Texas Education Agency)
What the exam covers
- Number and algebraic methods
- Describing and graphing linear functions, equations and inequalities
- Writing and solving linear functions, equations and inequalities
- Quadratic functions and equations
- Exponential functions and equations
The most common mistakes, unit by unit
Number and algebraic methods
- Combining unlike terms. Combining like terms →
- Adding exponents on different bases. Exponent rules for multiplying powers →
Describing and graphing linear functions, equations and inequalities
- Misreading the slope from a rearranged equation. Reading slope-intercept form →
- Plotting the slope as a point. Graphing a line from its equation →
Writing and solving linear functions, equations and inequalities
- Dividing only one term. Dividing both sides to isolate x →
- Forgetting to flip the inequality. Flipping the inequality when dividing by a negative →
- Substitution slips in systems. Solving a system by substitution →
Quadratic functions and equations
- Sign errors when factoring. Factoring quadratics into two brackets →
- Using zero-product before setting the equation to zero. Solving quadratics with the zero-product rule →
Exponential functions and equations
- Treating repeated multiplication (growth) as repeated addition.
