Number Cards 1–20: The Essential Guide To Teaching Numbers Faster With Powerful Flashcards

• Discover fun, proven ways to teach 1–20 using digital number cards that kids actually enjoy.

Why Number Cards 1–20 Matter More Than You Think

If you’re teaching a kid numbers 1–20 (or learning them in a new language), simple number cards 1–20 are one of the easiest wins you can use.

They help with:

• Recognizing numbers quickly
• Counting in order (and backwards)
• Understanding “how many” a number actually means
• Getting ready for addition, subtraction, and place value

Instead of printing a million worksheets, you can turn numbers 1–20 into interactive flashcards on your phone with an app like Flashrecall:

It’s basically number cards 1–20 on steroids: you can add pictures, sounds, examples, and it reminds you when to review so kids don’t forget.

Let’s walk through how to use number cards 1–20 properly, and how to make them way more powerful using Flashrecall.

What Are “Number Cards 1–20” Really For?

Number cards 1–20 are just cards showing the numbers from 1 to 20. But the magic is in how you use them:

• Number recognition – see “14” and instantly know it’s fourteen
• Counting practice – putting them in order, forwards and backwards
• Quantity understanding – connecting “7” to a group of 7 things
• Language – saying the number out loud (great for ESL or kids learning to speak)

You can absolutely use physical cards, but digital number cards have some big advantages:

• You always have them with you (phone/iPad)
• You can add images (7 apples, 12 stars, etc.)
• You can add audio (say the number out loud)
• You can track progress and use spaced repetition so the numbers actually stick

That’s where Flashrecall comes in.

Why Use Flashrecall For Number Cards 1–20?

Here’s how it helps specifically with number cards 1–20:

• Create cards in seconds
• Type “1” on the front and “one 🍎” on the back
• Or use images, PDFs, or even screenshots of worksheets and let Flashrecall turn them into cards
• You can even paste a YouTube kids math video link and pull ideas from it
• Active recall built in

Flashrecall hides the answer so the learner has to remember the number or say it out loud before flipping. That’s exactly what you want with number cards.

• Spaced repetition & reminders

Flashrecall automatically schedules reviews so kids see 5, 11, or 17 right before they’re about to forget them. You don’t have to remember what to review when—the app does it.

• Works offline

Perfect for car rides, waiting rooms, or anywhere you don’t want to carry a stack of cards.

• Chat with the flashcard

Stuck? You can literally chat with the card and get explanations or extra examples (e.g., “show me 14 with objects”).

• Free to start, fast, and simple

Works on iPhone and iPad, and it’s very kid‑friendly.

How To Set Up Number Cards 1–20 In Flashrecall

Step 1: Create A Deck Called “Numbers 1–20”

In Flashrecall:

1. Create a new deck: “Numbers 1–20” or “Counting Practice”.

2. This keeps everything in one place and easy to review.

Step 2: Make Simple Number Cards

For each number, you can create a basic card:

• Front: `7`
• Back: `seven`

Or, for younger kids, make it more visual:

• Front: `7`
• Back:
• Text: `seven`
• Image: picture of 7 apples or 7 stars
• (Optional) Audio: record yourself saying “seven” slowly and clearly

You can:

• Add images directly
• Import from PDFs or screenshots (e.g., a worksheet with numbers) and let Flashrecall turn them into cards
• Type prompts like “Create number flashcards 1–20 with examples” and build off that

Step 3: Add Quantity To Each Card

To really make the numbers stick, connect the symbol to a quantity:

• Front: `12`
• Back:
• “twelve”
• A picture of 12 circles
• A sentence: “There are 12 months in a year.”

This helps kids understand that 12 isn’t just a shape, it means “twelve things.”

Fun Ways To Use Number Cards 1–20 With Kids

Here are some simple, effective games you can play—digital or physical.

1. “What Comes Next?” Game

In Flashrecall, show a card:

• If the card shows 8, ask:
• “What comes before 8?”
• “What comes after 8?”

You can:

• Put that on the back of the card as a reminder
• Or just ask it out loud every time

This builds number order and mental number lines.

2. “Show Me That Many”

Use the card as a prompt, then:

• Show 5
• Ask the child to clap 5 times, jump 5 times, or draw 5 dots

You can add instructions to the back of the flashcard like:

> “Do 5 claps” or “Draw 5 stars in your notebook.”

Even though the action happens outside the app, the card is the trigger.

3. Odd vs Even Challenge

Once they’re a bit more advanced:

• Front: `14`
• Back:
• “Fourteen”
• “Even number”
• Example: “14 socks can be paired.”

Ask: “Is 14 odd or even?” before flipping.

Using Number Cards 1–20 For Language Learning

If you’re learning English (or any other language), number cards 1–20 are a super easy vocabulary win.

You can make cards like:

• Front: `3`
• Back:
• English: `three`
• Spanish: `tres`
• Example sentence: “I have three cats.”

Or:

• Front: `six – 6`
• Back:
• Audio of you saying “six”
• Translation in your native language

In Flashrecall, you can:

• Add multiple languages on the same card
• Use chat to ask: “Give me example sentences using the word ‘seven’” and paste them into your cards

How Spaced Repetition Makes 1–20 Stick (Without Extra Effort)

The big problem with teaching numbers is this:

Kids learn them once, seem fine… and a week later, 13 and 15 are suddenly gone.

• Showing easy numbers less often
• Showing tricky numbers (like 11, 12, 13) more often
• Spacing reviews just before forgetting happens

Flashrecall has spaced repetition and reminders built in, so you don’t have to track anything manually.

What this looks like day to day:

• Day 1: You review all numbers 1–20
• Day 2: You mostly see the ones they struggled with
• Day 4, 7, 14, etc.: The app brings the cards back at the right times

Result: numbers 1–20 move from “I think I know this” to “automatic.”

Example: A Simple Flashrecall Setup For Numbers 1–20

Here’s a mini blueprint you can copy:

Card Type 1 – Basic Recognition

• Front: `9`
• Back:
• “nine”
• Picture of 9 balloons

Use this for: “See the number → say its name.”

Card Type 2 – Word To Number

• Front: `sixteen`
• Back: `16`

Use this for: reading/writing practice (especially for tricky teens like 13, 14, 15, 16).

Card Type 3 – Quantity Match

• Front: Image of 4 apples
• Back: `4` – “four”

Use this for: connecting “how many” to the symbol.

You can easily create these by:

• Snapping a photo of a worksheet or drawing and letting Flashrecall turn it into cards
• Or importing images directly into the app

Tips To Make Number Cards 1–20 Actually Fun

A few simple tweaks can make a big difference:

1. Keep sessions short

5–10 minutes is plenty for kids. Flashrecall makes it easy to do quick, daily reviews instead of one long session.

2. Mix old and new

Don’t just drill 11–20. Mix in 1–10 so kids feel successful and see the full number range.

3. Use rewards

After a review session, do something small: a sticker, a high‑five, or “you pick the next game.”

4. Let kids help make cards

In Flashrecall, let them:

• Choose the images
• Record themselves saying the numbers
• Pick colors or emojis for the back

When kids help create the cards, they remember better.

5. Practice backwards

Try counting from 20 down to 1 using the flashcards. Great for mental flexibility.
