The game tracks points earned and supports multiple players.
Kids practice skills related to summer sense and ordering.
Each book includes nine chapters filled with worksheets.
Fraction models help kids visualize parts of a whole.
Puzzles encourage kids to use critical thinking skills.

Pros: Kids can practice a wide range of math skills and rise in the ranks of an imaginary kingdom's social structure.

Cons: More advanced levels aren't accessible until less challenging levels are completed, which may be an issue for more advanced learners.

Bottom Line: With a fun premise and tons of good math problems, this is a solid practice tool for kids with a wide range of abilities.

How Can I Teach with This Tool?

In the classroom, use the King of Math Junior worksheets as post-lesson practice tools. As a class, discuss the virtual medieval society and challenge kids to earn stars and eventually assume the role of king or queen. Leaderboards can be tracked through Game Center, or you can keep your own class leaderboard. The game accommodates multiple players, so kids can share devices if needed.

Standards:

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. Practice worksheets are organized by content areas, including basic counting and addition and more advanced concepts like multiplication, division, and fractions. 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 chapter. Throughout these books, kids practice addition, subtraction, number sense, geometry, multiplication, division, measurement, and fractions. In a book called "Puzzles," kids practice reasoning and critical-thinking skills.

As kids continue to earn points for correct answers, they earn stars and level up their characters from farmers to more powerful members of society. 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 sets in the full paid version.

The unique setting and objective -- answer math problems correctly and you could rule the land! -- makes King of Math Junior a fun, engaging way to get kids to practice important math skills. The content is rich, and the worksheets and scoring system fill this practice tool with meaningful learning experiences and positive rewards. Different models are used to represent many of the same types of problems: For example, addition problems are represented as standard math sentences, number cubes, and groups of fruit on plates, offering a great opportunity to reinforce comprehension for young learners. These learning opportunities would be even better if the feedback were richer; as it is, the only feedback for incorrect answers is a big red X. Richer, more detailed feedback -- and access to hints periodically -- would make this engaging experience even more encouraging for students of all abilities.

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

Kids will have fun climbing the social ladder and transforming from a lowly farmer into a king or queen. Most worksheets offer colorful, interactive problems.

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

Challenges increase in difficulty and cover a wide range of skills. Worksheets model multiple representations of several concepts, helping kids build comprehension.

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 can view their overall scores and rewards, but detailed learning progress isn't tracked.

Key Standards Supported

Counting And Cardinality

  • K.CC.5

    Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.

Measurement And Data

  • 1.MD.3

    Tell and write time in hours and half-hours using analog and digital clocks.

Number And Operations—Fractions

  • 3.NF.1

    Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

Operations And Algebraic Thinking

  • K.OA.2

    Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

  • 1.OA.6

    Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

  • 3.OA.7

    Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
