Questions

Do I need an account to try them?

No. The 10 sample cards in every deck are free for everyone, with no sign-in.

Which devices do they work on?

Any phone, tablet, Chromebook or computer with a modern web browser. On a phone, you can add the page to your home screen to open it like an app.

Is the voice a real person?

No. The cards use the voice built into your device, set to sound friendly and upbeat. If your device has no Spanish or Portuguese voice installed, it reads with the closest voice it has.

How many cards are in a deck?

Math decks have 60 to 225 cards: each fact appears forward, turned around and with a missing number. Vocabulary decks have 5–345 words each, one deck per subject and grade.

How do flashcards earn reward points?

Members earn 1 point a day for a mastered round: 20 cards with at least 80% marked “I knew it” on the first try. A round under 80% earns no point, so being honest is what makes the point count.

Which vocabulary decks are there?

Reading, Writing, Science, Social Studies, Life Skills, Entrepreneurship and Psychology words from Kindergarten to grade 8, and Math words from Kindergarten to grade 8, in English, Spanish and Portuguese. The words and meanings come from our own lessons, so the cards match what your student is learning.

Why flashcards work: the research

Each part of these cards comes from published research on how students remember. The numbers point to the reference list below.

  1. Trying to remember comes first

    The answer is hidden until your student has tried. Recalling something from memory strengthens it more than reading it again: students who practiced recalling remembered far more a week later than students who spent the same time restudying.[1]

  2. Two of the most useful ways to study

    A review of ten common study methods rated practice testing and spreading practice over time as the two most useful, for students of many ages.[2]

  3. One big deck beats small piles

    In a flashcard study, going through one stack of 20 cards, so each card came back after a gap, beat studying four small piles of 5 for about 90% of learners. That is why our decks mix many facts, and why a missed card comes back a few cards later instead of right away.[3]

  4. A few minutes on several days

    Practice spread over several days is remembered longer than the same amount in one sitting. Ten or twenty cards a day works better than a hundred once a week.[4][2]

  5. The right answer, right away

    Flipping shows the correct answer at once, with a short tip. Feedback helps most when it tells the student what is right and how to get there.[5]

  6. Why math facts are worth memorizing

    The National Mathematics Advisory Panel recommended that students recall basic facts, including multiplication and division, quickly and effortlessly, so their attention is free for harder problems.[6]

  7. Pictures with words (vocabulary decks)

    Students learn more from words and pictures together than from words alone. Our vocabulary decks put a picture next to each word and read it aloud.[7]

What we don't claim

Flashcards are for practice, not for teaching a new idea. Teach the concept first (every UpOnly Learning math lesson does, with pictures and worked examples), then use the cards to make the facts quick and automatic. Every student learns at their own pace.
