Real Math. Real Standards. Zero Data Collection.
Math Crusher is built around the U.S. Common Core standards for Grades 1 through 6. Every math problem your child sees is grade-appropriate and covers real topics they need to master — not random trivia.
The game covers addition, subtraction, multiplication, division, fractions, decimals, geometry, measurement and conversions, place value, order of operations (PEMDAS), volume, word problems, rounding, patterns, ratios, percentages, statistics, and negative numbers.

How it Works
Step 1: Pick Your Grade
Choose from Grade 1 through Grade 6. All math problems automatically adjust to your child's level based on Common Core standards.
Step 2: Choose Your Avatar
Pick from 6 characters — Knight, Ninja, Elf, Wizard, Skater, or Pirate — and jump into the world.
Step 3: Mine, Fight, Learn
Dig through layers of ore, each one tied to a different math topic. Fight monsters that quiz you on multiplication, fractions, geometry, and more. Collect rare gems for special boss-fight powers.
Step 4: Defeat the Boss
Reach the bottom, face the Boss, and use everything you've learned (and collected) to win.

Black Hawthorn Ventures is an independent studio based in California focused on building tools and apps that make learning practical, fun, and private. Math Crusher is our first product — built from the ground up by a parent who wanted something better for their kid.
We believe educational apps should teach real skills, respect families' privacy, and never treat children as data points. That is why Math Crusher collects zero personal information, runs entirely offline, and follows every math problem back to actual Common Core standards.
