The parents' guide to what's in this app.

Educational Value

Kids can learn about addition, subtraction, number sense, geometry, multiplication, division, measurement, and fractions. In a book named Puzzles, kids practice reasoning and critical-thinking skills. Different models are used to represent many of the same types of problems, which is a good way to reinforce comprehension for young learners. Though the game provides rich content and plenty of positive rewards, the only feedback for incorrect answers is a big red X. Although this is intended as a practice tool, struggling kids would benefit more if they could access a hint for each worksheet. King of Math Junior is a solid math tool that addresses a wide variety of skills.

Ease of Play

Play is simple; just tap on the correct answer. Basic icons for settings, rewards, and user profiles make navigation super intuitive.

Violence & Scariness

When tapped, a childproof ad in the corner of the home screen takes users to the app store.

What parents need to know

Parents need to know that King of Math Junior is a game that revolves around a virtual medieval society. As kids answer questions correctly and solve puzzles, they climb the so-called social ladder in the hopes of becoming king or queen. Worksheets cover a range of math topics and often incorporate models to help kids understand the concepts rather than simply having them memorize them. Kids can earn medals and stars and use Game Center to play with friends. There are 19 in-app languages including English, Danish, German, Spanish, and more; see the developer's website for a full listing.

What's it about?

KING OF MATH JUNIOR is a set of drill-style worksheets that are organized by content. Each set of worksheets is called a book, and each book contains nine chapters. Kids have to earn a minimal score to unlock a chapter and move on to the next. As kids continue to earn points for correct answers, they earn stars and level up their characters from farmers to more powerful members of the virtual medieval society. It's fun for kids to take on these roles, and the math content ranges from basic counting and addition to more advanced concepts such as multiplication, division, and fractions. The game links with Game Center, but this setting can be turned off. A free version of the app is available, but it only contains three sets of worksheets (Counting, Addition, and Subtraction) compared to 10 in the full paid version.

Is it any good?

The unique setting of a virtual medieval society is a fun and engaging way to get kids to practice important math skills. One of the best features of this game is that each skill is presented in a different way. For example, kids practice fraction skills using circle models, bar models, and number lines. The reward system is motivating, and a wide range of content is covered. It would be great to see a way to track kids' learning progress; a report might show how many problems kids got wrong in specific content areas, and a comparative report could identify strengths and weaknesses. Also, math drills alone aren't the most innovative way to get kids practicing math, but the added features are just motivating enough to make this an interesting way to bolster skills.

Talk to your kids about ...

  • Families can talk about medieval societies and how people from that time period may have used math skills.

  • Challenge kids to earn one new societal ranking per day until they reach king or queen.
