How to Use These TExES Core Subjects EC-6 Math Flashcards
1
Pick one topic
Use the topic dropdown instead of facing all 83 cards at once. Start with the topics you find hardest.
2
Flip, then mark
Read the front, say the rule or definition out loud, then flip. Mark Know it only when you can explain it, not just recognize it.
3
Practice right away
After a set, solve a few problems that use those rules. Flashcards build recall; worked practice turns them into test-day tools.
Best Order for Studying
If the deck feels like a lot, study the foundational topics first, such as numbers, fractions and percents, and exponents, then move on to algebra, geometry, and data, and review the test facts last. This moves from the skills every other topic builds on to the ones that appear in specific problem types.
Most Important Formulas and Facts to Know First
- Order of operations: the sequence that keeps every calculation consistent.
- Exponent rules: product, quotient, power, zero, and negative exponents.
- Fraction operations: and converting between fractions, decimals, and percents.
- Percent of a number and percent of change: the backbone of word problems.
- Slope and slope-intercept form: for reading and writing linear graphs.
- Area, perimeter, and volume: the core geometry formulas.
- The Pythagorean theorem: for right triangles and distance.
- Factoring and the quadratic formula: for solving quadratics.
- Mean, median, mode, and range: the four measures that summarize data.
- Probability of an event: favorable outcomes over total outcomes.
Common Mistakes These Cards Help Fix
- Ignoring order of operations and simply working left to right.
- Adding or subtracting fractions without a common denominator.
- Confusing area with perimeter, or surface area with volume.
- Flipping an inequality sign at the wrong time, instead of only when multiplying or dividing by a negative.
- Mixing up mean, median, and mode.
- Treating a negative exponent as a negative number instead of a reciprocal.
- Applying the Pythagorean theorem to triangles that are not right triangles.

Check the official TExES site for current timing and policies.
What are the TExES Core Subjects EC-6 math competencies?
The TExES Core Subjects EC-6 math competencies cover number concepts and operations, patterns and algebra, geometry and measurement, probability and statistics, and mathematical processes and teaching. In practice that means knowing skills like place value and fraction models, and being able to explain them, such as showing why 1/2 = 2/4 with a drawing.
Is there a free TExES Core Subjects EC-6 practice test?
Yes, free TExES Core Subjects EC-6 practice questions are available, and the official preparation manual includes sample items for the math subtest. Take a timed set, then list every missed skill. If unit conversions or percent problems were the problem, filter this deck to those cards and study them daily before your next practice set.
Is there a free TExES Core Subjects EC-6 (391) study guide?
Yes, the official TExES preparation manual for Core Subjects EC-6 (391) is free and available as a PDF. It lists every competency and includes sample questions with explanations.
