Flashcards Numbers 1–20: The Essential Trick To Help You (Or Your Kid) Remember Numbers Fast

Master numbers 1–20 with simple, fun flashcard techniques most people never use—but should.

Why Flashcards For Numbers 1–20 Actually Work

If you (or your kid) are still getting stuck on basic numbers like 7 vs 17, or 14 vs 40, flashcards are honestly one of the easiest fixes.

They’re simple, repeatable, and perfect for short attention spans.

And if you use a smart flashcard app instead of paper cards, it gets way easier to stay consistent. That’s where Flashrecall comes in:

Flashrecall lets you:

• Quickly make number flashcards (with images, audio, or text)
• Get automatic spaced repetition so you actually remember them
• Study in short bursts on iPhone or iPad, even offline

Perfect for kids… and honestly for adults learning a new language too.

Let’s walk through how to use flashcards to nail numbers 1–20, step by step.

Step 1: Decide What “Number 1–20” Actually Means For You

“Flashcards numbers 1–20” can mean different things depending on what you’re trying to learn:

• A child learning to recognize and say numbers (1, 2, 3…)
• Someone learning numbers in another language (uno, dos, tres…)
• Someone who needs to connect numerals, words, and quantity (3 ↔ “three” ↔ 🐻🐻🐻)

Figure out what you want your flashcards to do:

• Just recognize digits?
• Read and say them out loud?
• Match number → spelling → quantity?
• Or do it in another language?

Once you know that, you can design way better cards.

Step 2: What Kind Of Flashcards Should You Make?

Here are some super simple, effective flashcard types for numbers 1–20.

1. Numeral → Word

This is the classic. Great for:

• Young kids learning to read numbers
• Anyone learning numbers in a new language

In Flashrecall, you can:

• Type the number on the front
• Type the word on the back
• Add audio of you saying it (or have AI help you if you’re learning a language)

2. Word → Numeral

Flip it around to make sure the brain works both ways.

This helps with:

• Spelling
• Reading
• Fast recognition

In Flashrecall, just duplicate the first card and swap front/back. Takes seconds.

3. Number → Quantity (Great For Kids)

You can do:

• Photos of real objects
• Simple dot patterns
• Fun icons or emojis (if you’re making paper cards, draw them)

With Flashrecall you can:

• Take a photo of 4 toys or 7 blocks
• Turn that image into a flashcard instantly
• Or upload a PDF/worksheet and auto-generate cards from it

4. “Tricky Pairs” (14 vs 40, 15 vs 50, etc.)

Some numbers always trip people up.

Make special cards just for those:

Or for another language:

You can even add a little hint or mnemonic on the back:

> “teen = ends in -teen = 10 + something”

Flashrecall is great here because you can:

• Add extra explanation in the back of the card
• Or chat with the flashcard if you’re confused and want more examples

Step 3: How To Make Number Flashcards Super Fast (Without Going Crazy)

If you’re making physical cards, it’s easy to burn out writing “sixteen” for the 10th time.

With Flashrecall, you can speed this up massively:

• Type a list:

`1 one`

`2 two`

`3 three`

… all the way to 20

and turn them into flashcards in seconds.

• Or paste from a text file / note.
• Or even use a PDF or worksheet and let the app generate cards from it.

Flashrecall can make flashcards from:

• Text
• Images
• Audio
• PDFs
• YouTube links
• Or just stuff you type manually

It’s free to start, so you can test it with just your numbers 1–20 set first.

Step 4: Use Active Recall (Don’t Just Stare At The Cards)

The whole point of flashcards is active recall: you look at the front and actually try to remember the answer before flipping.

So when you see:

> Front: `13`

Do this:

• Pause for a second
• Say out loud: “thirteen”
• Then flip and check

Flashrecall is built around active recall by default:

• It shows you the front
• You think of the answer
• Then you tap to reveal the back and rate how hard it was

No passive scrolling. Your brain has to do the work, which is how memory sticks.

Step 5: Let Spaced Repetition Do The Heavy Lifting

This is the part most people skip—and it’s why they forget.

You don’t need to review all 20 number flashcards every day forever.

You just need to review:

• Hard cards more often
• Easy cards less often

That’s exactly what spaced repetition does.

With Flashrecall:

• You rate how well you remembered each card (easy / medium / hard)
• The app automatically schedules the next review
• You get study reminders, so you don’t have to remember to remember

So if:

• `7` is easy → you’ll see it less often
• `17` is hard → you’ll see it again soon

Over time, you basically train your brain to instantly recognize all numbers 1–20 without overstudying.

Step 6: Keep It Short, Fun, And Consistent

Especially if you’re doing this with a kid, shorter is better.

Aim for:

• 5–10 minutes per session
• Once or twice a day

Some ideas:

• Do a quick session during breakfast
• Another one before bed
• Turn it into a “race” to see how many correct in a row

Flashrecall makes this easy because:

• It works offline (perfect for car rides, waiting rooms, etc.)
• It’s fast and modern, so kids don’t get bored tapping through clunky screens
• It syncs on iPhone and iPad, so you can use whatever’s nearby

Why Use Flashrecall Instead Of Paper Cards?

Paper cards are fine, but:

• You have to organize them manually
• You forget to review them
• They get lost / bent / eaten by the dog

If you’re going to spend time making number flashcards anyway, might as well have an app that does the scheduling and reminding for you.

Quick Game Ideas Using Flashcards 1–20

To keep things fun, especially for kids:

1. “Find The Number”

• Show the word: “seventeen”
