How to use Flash Cards

  1. Choose a vocabulary deck that matches your English level or learning goal.
  2. Read the word on the front of the card and try to recall its meaning before flipping.
  3. Tap or click the card to reveal the definition and example sentence on the back.
  4. Click Known if you remembered it correctly, or Still Learning if you need more practice.
  5. At the end of the deck, review only the words you didn't know — repeat until you know them all.

Why Flash Cards work for vocabulary learning

Flash cards are one of the most well-researched methods for learning new vocabulary. The technique is based on active recall — the mental effort of retrieving a memory — which strengthens neural pathways far more effectively than re-reading.

When you see a word and try to recall its definition before flipping, you activate a memory retrieval process. Whether you succeed or fail, the act of trying embeds the information more deeply than passive reading would.

Study tip: Say the word out loud before you flip the card. Speaking activates a different part of your brain and adds a second encoding pathway, making the word easier to recall later.

Spaced repetition: smarter studying

LexFizz's flash card system uses a simplified spaced repetition model. Cards you mark as "Known" are set aside, while "Still Learning" cards are shown again. This mirrors the science behind forgetting curves — you review difficult material just before you would forget it, turning short-term exposure into long-term memory.

After completing a deck, use "Review Unknown Only" to focus exclusively on your problem words. Typically, 3–4 review rounds are enough to move a new word into long-term memory.

CEFR level guide

Each card is tagged with its CEFR level — the international standard for English proficiency:

  • A1–A2 (Beginner): Core everyday words — greetings, family, colours, numbers, basic actions.
  • B1–B2 (Intermediate): Travel, work, opinions, abstract concepts, common idioms.
  • C1–C2 (Advanced): Academic vocabulary, nuanced expressions, formal language, business terminology.

Tips for effective flash card sessions

  • Keep sessions short: 10–15 minutes once or twice a day outperforms one long weekly session.
  • Context over translation: Try to understand the definition in English rather than translating to your native language.
  • Say it aloud: Pronunciation practice combined with meaning recall doubles retention speed.
  • Create mental images: Visualise the word in action. A vivid mental picture creates a stronger memory hook.
  • Shuffle regularly: Predictable card order lets you rely on sequence rather than true recall. Use the Shuffle button often.

Frequently Asked Questions

How do I use the Flash Cards exercise?
Select a vocabulary deck, then read the word on the front of each card. Try to recall its meaning before you flip. Tap or click the card to reveal the definition and an example sentence. Mark the card as Known if you got it right, or Still Learning if you need more practice. Work through all cards, then review only the ones you did not know.
Does LexFizz use spaced repetition for Flash Cards?
LexFizz uses a simplified spaced repetition model. Cards marked as Still Learning are kept in the active deck and shown again, while Known cards are set aside. At the end of a session you can choose Review Unknown Only to focus exclusively on the words you have not yet mastered, repeating the cycle until all are known.
How many cards are in each flash card session?
Deck sizes vary by topic. Most decks contain 15–20 cards. The Everyday English, Academic Vocabulary, Phrasal Verbs, IELTS Vocabulary, and Irregular Verbs decks each contain 20 cards. The Common Idioms deck has 15 cards and the Business English deck has 18 cards.
Are the flash cards labelled with CEFR levels?
Yes. Every card displays a CEFR level badge (A1 through C2) in the top-right corner of both the front and back. This helps you identify which words belong to your current level and which are a stretch goal for the next level up.
What is the difference between Known and Still Learning?
Known means you successfully recalled the definition before flipping the card — the word is moving into your long-term memory. Still Learning means you needed the flip to remember it, or were not confident. Honest self-assessment here is crucial: only mark a card Known when you are truly sure.
Why do flip-cards build vocabulary better than passively reading a list?
Flip-cards require active recall — the cognitive effort of retrieving a memory — which strengthens neural pathways far more than re-reading. The act of trying to remember before seeing the answer creates a desirable difficulty that accelerates long-term retention, even when you fail to recall correctly.
Can I use Flash Cards to practise pronunciation?
Yes. Each card shows an IPA phonetic transcription below the word on the front face. Before you flip the card, say the word aloud using the phonetic guide. Speaking activates a different memory pathway and combining pronunciation with meaning recall doubles retention speed compared to silent study.
How many vocabulary decks are available?
There are eight decks: Everyday English (A1/A2), Travel and Places (A2/B1), Academic Vocabulary (B2/C1), Common Idioms (B1/B2), Business English (B2/C2), Phrasal Verbs (B1/C1), IELTS Vocabulary (B2/C1), and Irregular Verbs (A2/B2). New decks are added regularly.
Can I study Flash Cards offline?
Yes. All card data is embedded in the page itself. Once the page has loaded fully in your browser, you can disconnect from the internet and continue studying without interruption. Avoid refreshing the page while offline as that would require a new download.
How do LexFizz Flash Cards compare to Anki?
Anki uses a full spaced repetition algorithm that schedules cards days or weeks apart based on your performance history. LexFizz Flash Cards are session-based and require no account or setup — ideal for quick in-browser practice. Use LexFizz to discover and learn new vocabulary sets, then transfer words you want long-term drilling into Anki for deep scheduling.
