A deck of cards costs 30 kr. It contains 52 cards + 2 jokers. With it you can play 20+ maths games with your child. No other dirt-cheap material beats a deck of cards for maths training at home. This article lists the best card games sorted by age and what they train.
At Kluriko maths is trained digitally in the Learning Games — but a deck of cards on the kitchen table gives something else entirely: physical handling, family context, turn-taking, face-to-face.
Set-up
Deck of 52 cards:
- 13 in four suits (clubs, diamonds, hearts, spades)
- Cards 2-10 plus jack (J), queen (Q), king (K), ace (A)
For maths: use Ace = 1, J = 11, Q = 12, K = 13. Or — for simpler games — remove the picture cards and play with 2-10.
For 3–5-year-olds
1. Snap
Classic. Two piles face-down. Each flips one card at a time. Both the same — call "Snap!". Trains:
- Pattern recognition
- Quick reaction
- Number comparison
2. Memory with cards
Lay out 20 cards face-down. They flip two. Match? Keep the pair. Trains:
- Visual memory
- Classification
3. Higher or lower
You flip a card, they flip one. Who has the bigger? Trains:
- Number comparison
- Number recognition
4. Sorting
They sort the cards:
- By suit
- By value
- By suit and value
Trains:
- Classification
- Number range
For 5–7-year-olds
5. War
Like "higher or lower" but with the whole deck. Winner takes both cards. Most cards wins. Trains:
- Number comparison
- Quick counting
6. The ten-game
Lay out 9 cards in a grid. They find two that make 10 (number bonds!). Remove. Lay new ones. Trains:
- Number bonds to 10 — CRITICAL
- Fast addition
7. Black Jack (simplified)
Two cards each. Closest to 21 wins. Trains:
- Addition under 21
- Probability
8. Yatzy with cards
Flip 5 cards. Add up. Highest wins. Trains:
- Addition
- Strategy
9. Order race
Shuffle cards 1-10. They lay them in order as fast as possible. Trains:
- Number sequence
- Speed
10. Multiplication snap
Flip two cards. Who says the product first? Trains:
- Multiplication
- Fast mental math
For 7–9-year-olds
11. Bridge for kids
Simplified bridge. Trains:
- Strategy
- Counting
- Probability
12. Phase 10
Complex card game. Trains:
- Sorting
- Strategy
- Counting
13. UNO with addition rule
The last person holding cards adds up the values. Trains:
- Fast addition
14. Addition tower
You and they lay cards alternately. Both add to a pot of 100. First to 100 wins. Trains:
- Large-number addition
- Strategy
15. Subtraction game
They start with 100 points. Subtract card value each turn. First to 0 wins. Trains:
- Subtraction
- Negatives (if past 0)
For 9+
16. Skat (or similar trick-taking)
Classic trick-taking games. Train:
- Strategy
- Counting
- Complex rules
17. Bridge
Adult game they can start learning. Trains:
- Logic
- Probability
- Partnership
18. Pinochle
As complex as bridge. Trains:
- Counting
- Strategy
19. Math War
Advanced War: flip two cards, add. Largest sum wins. Trains:
- Fast addition
20. Equations
Lay cards and build equations. "4 + 5 = 9". Trains:
- All basic arithmetic
How often?
Three times a week, 15 minutes. Not longer — card games should be snack-games, not big engagements.
At dinner, before bed, rainy afternoons are classic times.
What makes card games so good?
Physical. They touch cards, shuffle, deal. Active.
Social. You, them, maybe siblings. Family time.
Repeatable. The same game can be played a hundred times.
Adjustable. You can make it harder or easier depending on their level.
Discreet maths. They don't know they're training — they're playing.
Common problems
They lose and get cross. Play team games instead. You and them vs nobody.
The cards get lost. Buy 2-3 decks. Or a magnetic version that doesn't blow away.
They tire of the same game. Vary. 5 games in rotation keeps it fresh.
A ten-week plan
Week 1-2: Snap, Memory, Higher or Lower. Week 3-4: War, Sorting. Week 5-6: Ten-game, simplified Black Jack. Week 7-8: Yatzy with cards, Order race. Week 9-10: Multiplication snap, Phase 10.
Within ten weeks: their basic mental maths is much better.
