On screen
Beat-the-clock rounds and instant feedback build speed — and the itch to keep practicing.
On the table
The printed deck & activities turn that momentum into screen-free, face-to-face play that sticks.
Two halves of one system — the online game motivates daily practice and complements every printed deck and activity.
Three ways to practice.
Best of both worlds.
Same ten minutes, very different payoff. Here's how Number Battles stacks up against the usual options.
Drill & kill
worksheets & flashcards
- ✓ Builds fast fact recall
- – …but it's rote and repetitive
- – Silent, solo, easy to dread
Screen math games
apps & video games
- ✓ Fun, with instant feedback
- – …but passive and easy to zone out
- – Ads, distractions, more screen time
Number Battles
disguised numbers — on screen & on the table
- ✓ The fluency of a drill, the fun of a game
- ✓ Decode & reason on every card
- ✓ Play on screen — a free, timed online game
- ✓ Play at the table — the printed card deck
- ✓ Self-checking — almost no prep
Number Battles takes the practice of a drill and the pull of a game — then lets you play it both on screen and across the table.
It feels like a game
Two cards clash, a timer ticks, someone wins the pile. The stakes do the motivating — you don't have to.
It builds real thinking
A rainbow means 7. Three pigs mean 3. Kids decode before they multiply — language and math firing together.
It brings them back to the table
No screens, no ads, no zoning out. Just a fast, loud, joyful fight over who knows their facts cold.
Built for classrooms & kitchen tables · Ages 7+ · Print & play
Numbers wear costumes.
Your brain does the unmasking.
Instead of cold digits, every card shows a fact from real life. Kids decode the number, then multiply or add. It works both sides of the brain — language and math — so word-lovers and number-lovers both get a foothold.

Decode the card
See “Continents.” Think 7. The picture is the clue; the value is the answer hiding underneath.

Battle the values
Two cards flip. Multiply them — 7 × 3 — and the first to shout 21 wins both cards.

Babe Ruth × Carbon — two themes, one battle
Where numbers clash and champions multiply.
Number Battle: General Engagement I reimagines the classic card game of War — but instead of flipping numbers, players flip picture-and-word clue cards, do the math in their heads, and race to shout the answer first. It's the fact practice kids actually ask to play.
The magic is in the four skill levels. The same 22-card deck comes in four flavors — from simple number-and-picture cards for brand-new learners up to word-only "expert" clues — so one game grows with your child and keeps a whole classroom or family in the fight. See it. Solve it. Say it. First to call the answer takes the card.
It's a print-and-play digital download, so there's no waiting on shipping: download, print, cut along the borders, and you're battling in minutes.
