Click Study Flashcards above to open the flashcard hub — hundreds of Praxis Core cards you can flip, match, type, or quiz yourself on. Every card is drawn from the three official Praxis Core subtests, so you study exactly what the test measures.[1] Pair them with our free practice test and study guide.
Praxis Core Flashcard Study Modes
Flip mode lets you study one card at a time and check yourself. Match turns terms and definitions into a timed pairing game. Type shows the definition and asks you to produce the term, so a card like Slope becomes a recall test rather than a recognition one. Quiz builds multiple-choice questions from the same cards, which is useful once the vocabulary already feels familiar.
Why Flashcards Work for the Praxis Core
Mathematics (5733) is the largest slice of the deck at 109 cards, so it is the natural place to spend the most time. The cards drill the number-sense and algebra vocabulary that shows up in word problems and in the wording of answer choices: LCM and GCF for working with factors and multiples, Slope for linear relationships, and Ratio for proportional comparisons. Statistics terms sit here too, with Mean, Mode, and Range appearing as separate cards so you do not confuse one measure for another under time pressure.
Writing (5723) carries 81 cards covering both the mechanics half and the essay half of the test. Punctuation gets direct attention through cards such as Comma and Colon, while sentence-level correctness shows up in Modifier, which is the vocabulary behind many of the usage questions. The essay side is represented by process and structure terms: Outline, Revision, and Editing name distinct stages rather than one blurred activity, and Hook and Citation cover how you open an argument and how you credit a source.
Reading (5713) holds 70 cards and focuses on the language used to describe passages and the questions asked about them. Cards like Fact, Claim, and Bias build the distinction between what a text states, what it argues, and how it leans, which is exactly what inference and evaluation items test. Author’s-craft vocabulary is covered by Tone, Mood, and Theme, and figurative language terms such as Idiom and Simile give you the words for questions about meaning beyond the literal.
The Praxis Core spans a lot of ground — reading and vocabulary, grammar and research skills, and math formulas and statistics.[1] Spaced flashcards are the most efficient way to keep it all fresh. Used alongside our practice test and study guide, they turn review time into measurable progress.
Praxis Core Flashcards by Subtest
The cards are organized by the three official Praxis Core subtests. Because each is passed independently, drill one subtest at a time — start with whichever you find hardest:
| Subtest | Questions | Test time |
|---|---|---|
| Reading (5713) | 56 selected-response | 85 min |
| Writing (5723) | 40 selected-response + 2 essays | 100 min |
| Mathematics (5733) | 56 selected-response | 90 min |
How to Get the Most Out of These Flashcards
- Start with Mathematics. It holds 109 cards, more than either other domain, so early sessions there move the largest share of the deck toward recall.
- Type-drill the confusable pairs. Cards such as LCM and GCF reward typed recall because recognizing them in a list is far easier than producing the right one from a definition.
- Use Match for the short label cards. Terms like Tone, Mood, and Theme pair quickly and the timer exposes which literary labels you are still guessing between.
- Switch to the practice test once Quiz feels easy. When multiple choice stops challenging you, move to full-length questions and use the study guide for any concept the cards only name.
- Work in domain-sized batches. Split the 81 Writing cards across several sittings, then revisit missed cards before adding new ones, rather than cycling all 260 in one pass.
Praxis Core Flashcards FAQ
Hundreds of free Praxis Core flashcards, organized across all three subtests — Reading (5713), Writing (5723), and Mathematics (5733). They cover the high-yield terms and concepts each subtest measures, and they're free with no account required.
Yes. Flashcards use active recall — pulling an answer from memory — which research shows is one of the most effective study methods, especially in short, spaced sessions. They're ideal for the Praxis Core's vocabulary, grammar rules, math formulas, and research-skills terms.
All three: Reading (main ideas, inference, vocabulary in context), Writing (subject-verb agreement, punctuation, research and citation, the two essays), and Math (percents, slope, the Pythagorean theorem, mean/median/mode). Drill one subtest at a time.
Focus on one subtest at a time, since each is passed independently. Mix the modes: flip to learn, type to test recall, match for speed, and quiz to check yourself before a full practice test. Drill your weakest subtest until the score clears the requirement.
