Start the game as a male or female farmer.
Users can adjust settings including player, sounds, language, and more.
Solve problems involving equations with variables.
Convert fractions to percents in the statistics book.

Pros: Timed activities and a fun theme motivate kids to boost math fluency.

Cons: No feedback is provided for incorrect answers, nor are there hints for struggling sudents.

Bottom Line: Students get solid math practice and build fact fluency with this worksheet-based virtual-society game.

How Can I Teach with This Tool?

A fun way to use King of Math would be to create a similar theme in the classroom while getting ready to use the worksheets as post-lesson practice tools. Hold a brief class discussion about the characters in the game, such as the farmer, jester, and king. Get kids excited about earning stars and the top character role. Leaderboards can be tracked through Game Center, or you can keep your own class leaderboard. The game accommodates multiple players, so kids can finish chapters independently while sharing devices, if necessary.

Standards:

In this math practice tool set in a virtual society, worksheets are organized by content. Each set of worksheets is called a book, and each book has nine chapters. Kids have to earn a minimum score to unlock a chapter and progress to the next chapter. As kids earn more and more points for correct answers, they earn stars and level up their characters from farmers to more powerful members of the society. Math content included in this fun and motivating theme game ranges from basic addition and subtraction to powers, statistics, and equations.

Users should note that there's an ad at the top of the screen, and players can easily access social media and the app store while playing the game. A free version of the app is available, but it only contains three sets of worksheets, compared to 12 sets in the full (paid) version. 

Although the standard "tap the correct answer" strategy is used throughout the game, there's quite a bit of variety in the question types, which is an effective way to challenge kids. Scoring and timing activities work well for building fluency. Overall, the game scores high on content and motivation. The only feedback students get for incorrect answers, however, is a big red X, which isn't helpful for struggling kids who could quickly get lost and feel overwhelmed.

Overall Rating
Engagement Is the product stimulating, entertaining, and engrossing? Will kids want to return?

Kids will have fun leveling up characters from farmers to possibly a king. Earning stars and points as the clock counts down is highly motivating. 

Pedagogy Is learning content seamlessly baked-in, and do kids build conceptual understanding? Is the product adaptable and empowering? Will skills transfer?

Each set of worksheets, called a book, has nine chapters that increase in difficulty. Books cover a wide range of core math skills. 

Support Does the product take into account learners of varying abilities, skill levels, and learning styles? Does it address both struggling and advanced students?

Kids are not offered formal instructions or help, but interactions are highly intuitive.

Key Standards Supported

Expressions And Equations

  • 6.EE.7

    Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

Geometry

  • 6.G.1

    Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

  • 7.G.4

    Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

The Number System

  • 6.NS.1

    Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?

Fun way to reinforce math operations!
I think this is a great app for individual student work. It allows for differentiation and for kids to work on their own pace. The problems vary in terms of difficulty level and are presented in different ways. The use of books allows students to master one concept before moving onto the next. It is also fun and motivating because kids move through different role levels as they master the concepts.
