When it comes to teaching your kids math skills, you've done it all: quizzes over breakfast, extra homework help, bedtime stories that sneak in math concepts. If you're looking for new, clever ways to help your kid gain the skills she needs, all you need is a smartphone. We've picked our 10 favorite math mobile apps for kids of different ages, all designed to teach four basic arithmetic operations (addition, subtraction, multiplication, division); some even meet Common Core State Standards. Download one (or all!) of these apps and we promise that your kid will hardly even know she's learning while playing.

Math Training for Kids

Three difficulty levels and the four basic concepts (addition, subtraction, multiplication, and division) in this simple app that teaches solid math fundamentals will help your child become more skilled. (Ages 3 and up; Free; Android)

Kids Math

The main task here is to pass all eight levels within a certain time frame by answering 10 math questions at each level (including ones about fractions and greater than/smaller than numbers.). Each question allows 30 seconds of answering time; for correct answers, players are rewarded with an additional four seconds. Dynamically generated questioning means that kids get new questions every time they play. (Ages 3 to 5; Free; Android)

Preschool Math Games for Kids

Young kids will get experience counting, tracing and reading numbers in a fun, interactive way. And don't let the name fool you! This app also features math exercises (addition, subtraction, sequence patterns, and more) for elementary schoolers-up to the 3rd grade level. (Ages 2 to 8; Free, Android)

Counting Caterpillar

Gorgeous colors and stunning visuals (plus cute caterpillars and butterflies!) on the display is enough to keep kids engaged. Feed the caterpillars by counting and catching aphids in the correct number sequence and earn butterflies (displayed in a gallery) to progress through more than 45 levels. (Ages 4 to 5; $1.99; iPhone, iPad)

Peter Pig's Money Coin Counter

Developed by Visa, this app helps kids practice sorting, counting, and identifying the value of U.S. coins to earn virtual money. Along the way, Peter Pig (a virtual piggy bank) helps kids learn facts about U.S. currency that are read aloud in a child's voice. (Ages 4 to 7; Free; Android)

Marble Math Junior

Solve a variety of math problems by collecting numbers and bonuses as you navigate a marble maze. With three difficulty levels and 16 marble styles, this app can be personalized to fit your kid's skills and personality. It also lets you customize games to concentrate on the areas in which your child needs the most help. (Ages 6 to 8; $3.99; iPhone, iPad)

Crazy Times Tables

Your child will love this app because of its fun, games, and photo features, but you'll love it too. The app takes a personalized approach by identifying his learning stage to help him master his times tables. (Ages 5 to 10; $2.99; iPhone, iPad)

Thinking Blocks Multiplication

Use number blocks to solve multiplication word problems, a strategy supported by Common Core standards. This app introduces kids to six problem solving models, which helps them organize information and visualize number relationships. (Ages 7 to 10; Free; iPhone, iPad)

Mathmateer

Mathmateer, voted one of the top 10 best apps for elementary school kids by Appolicious (the app directory), appeals to kids' creative side. To build a rocket ship to launch into space, kids must earn money by completing basic math challenges while recognizing patterns and shapes, telling time, and working on fractions and square roots. (Ages 9 to 11; $1.99; iPhone, iPad)
