DIY Number Flash Cards: Simple Ideas To Teach Kids Math Faster (Plus a Smarter App Shortcut) – Learn how to make diy number flash cards that actually help kids remember, and see how to level them up with a smart flashcard app.

What Are DIY Number Flash Cards (And Why They Work So Well)?

So, you know how diy number flash cards are just little cards with numbers or simple math on them? That’s really all they are: homemade cards you use to help kids learn counting, number recognition, and basic math in a fun, hands-on way. They work because kids remember better when they see, touch, and say the numbers instead of just staring at a worksheet. For example, a “7” card with seven stickers or dots makes “7” feel real, not just a symbol. And if you want to take those same ideas and make them digital with spaced repetition and reminders, you can turn them into smart flashcards in the Flashrecall app:

Why DIY Number Flash Cards Are So Good For Learning

Alright, let’s talk about why these simple little cards are actually super powerful:

• Kids learn by doing – Flipping cards, counting dots, tracing numbers… all that movement helps the brain remember.
• They’re visual – Colors, shapes, stickers, and pictures make abstract numbers feel concrete.
• You control the level – You can start with 0–10, then move to 11–20, then simple addition, subtraction, and so on.
• They’re cheap and quick – Paper, markers, scissors. Done.

The only downside?

You have to remember to use them consistently, and they can get lost, bent, or scattered all over the house.

That’s where it’s honestly nice to combine the DIY cards with something like Flashrecall. You can snap a photo of your physical card, turn it into a digital flashcard in seconds, and then the app reminds you when it’s time to review it again so your kid doesn’t forget.

Basic DIY Number Flash Cards: 0–10

Let’s start super simple.

What You Need

• Index cards or cut-up cardstock
• A black marker (plus colors if you want)
• Optional: stickers, dot markers, crayons, washi tape

How To Make Them

1. One number per card

On each card, write a big, clear number in the center: 0, 1, 2, 3, all the way to 10.

2. Add matching quantities

Under or around the number, show that amount:

• 3 dots for “3”
• 5 stars for “5”
• 7 stickers for “7”

3. Add the number word (optional)

Under the digit, write the word:

• “3” → “three”
• “9” → “nine”

4. Use color for patterns

Maybe all even numbers are blue, all odd numbers are red. This helps kids notice patterns like “2, 4, 6, 8…”

How To Use Them

• Lay out 0–10 and ask your child to put them in order.
• Show a card and ask, “What number is this?”
• Show the number and let them count the dots or stickers out loud.

Level It Up With Flashrecall

Once you’ve made a few, open Flashrecall on your iPhone or iPad:

https://apps.apple.com/us/app/flashrecall-study-flashcards/id6746757085

You can:

• Take a picture of each DIY card and instantly turn it into a digital flashcard.
• Add a simple question on the front like: “What number is this?”
• Put the image on the back so they can check themselves.

Flashrecall uses spaced repetition automatically, so the app will remind you to review “tricky” numbers (like 6 vs 9) more often, and easier ones less often. No manual tracking, no calendar needed.

DIY Number Flash Cards For 11–20 (And Beyond)

Once 0–10 feels easy, move up.

How To Make 11–20 Cards

• Same idea: one number per card, but now:
• Write “11” and “eleven”
• Draw 11 dots or use two rows (like 10 + 1) to start hinting at place value.

A Simple Place-Value Trick

For numbers like 14, 15, 16:

• Draw a group of 10 dots in one color.
• Draw the extra ones in another color.

So 14 might be:

• 10 blue dots + 4 red dots

This helps kids see that “14” is “ten and four,” not just a random word.

Practice Ideas

• Mix 0–20 and ask your child to sort them into:
• Less than 10
• 10–20
• Ask questions like:
• “What comes after 13?”
• “What comes before 17?”
• “Can you find the biggest number in this pile?”

Turning These Into Smart Flashcards

In Flashrecall, you can:

• Type cards manually (e.g., front: “What number comes after 13?” back: “14”).
• Or use text or images: snap a photo of your handwritten card, or just type the numbers.

Because Flashrecall has built-in active recall, each review is a quick quiz instead of just rereading. You see the question, try to remember, then flip the card and rate how hard it was. The app then schedules the next review automatically.

DIY Number Flash Cards For Basic Addition And Subtraction

Once your child knows the numbers, you can start playing with simple math.

Addition Cards

Make cards like:

• Front: `2 + 3 = ?`
• Back: `5`

Or use pictures:

• Draw 2 apples + 3 apples on the front
• Write “5 apples” on the back

Subtraction Cards

• Front: `7 – 2 = ?`
• Back: `5`

You can even draw 7 circles, cross out 2, and ask them to count what’s left.

Game Ideas

• Speed round: Flip through cards and see how many they can get in 1 minute.
• Sort by difficulty: “Easy” pile and “Hard” pile. Review the hard ones more.

How Flashrecall Helps Here

Instead of keeping a messy pile of math cards, you can:

• Type `2 + 3 = ?` into Flashrecall as the front
• Type `5` as the back
• Add an image if you want (like dots or apples)

Flashrecall:

• Reminds you to review these regularly with study reminders
• Shows harder cards more often using spaced repetition
• Works offline, so you can practice in the car, at a restaurant, wherever

It’s like a smarter version of your DIY number flash cards that you can’t lose or spill juice on.

Fun DIY Variations To Keep Kids Interested

If your kid gets bored easily, try changing how the cards look and how you use them.

1. Color-Coded Sets

• Green cards: numbers 0–10
• Yellow cards: numbers 11–20
• Red cards: “challenge” cards (bigger numbers or harder sums)

2. Themed Cards

• Use stickers: dinosaurs, cars, animals, stars
• For “5”, use 5 dinosaur stickers; for “8”, use 8 stars, etc.

3. Matching Games

Make two sets:

• Set A: numbers (1, 2, 3, 4…)
• Set B: pictures/quantities (1 apple, 2 cars, 3 stars…)

Lay them all face up and ask your child to match number to quantity.

You can then recreate this exact matching game in Flashrecall by:

• Making one card with the number on the front and the picture on the back
• Or vice versa, so they have to “guess” the number from the image

Blending DIY Cards With Digital: The Best Of Both Worlds

You don’t have to pick between physical diy number flash cards and an app. The combo is honestly the sweet spot:

Why Keep The DIY Cards?

• Kids like touching and flipping real cards.

• You can use it for any subject later: multiplication, spelling, languages, science, exams, whatever.

Flashrecall can also:

• Make flashcards from images, text, audio, PDFs, YouTube links, or typed prompts
