# Math Galaxy Fraction & Decimal Riddles App Review

Price: \$4.99

### Overview

Math Galaxy Fraction and Decimal Riddles provides users with identification and computation problems ranging from recognizing parts of a whole through operations with fractions, operations with decimals, operations with four types of measurement numbers, and calculation of angle measures using parallel lines. The format is game-like, set up for one to three players, and correct answers are rewarded with a score that represents “prize money,” similar to popular game shows. Correct responses reveal letters that eventually spell the answer to a riddle. Correct answers in the Jumble section reveal a hidden word from the scrambled letters.

Features include:

• Four skill areas
• Includes all four operations
• Two game types
• Multi-player capability
• Engaging reward system

### Quality

Math Galaxy Fraction and Decimal Riddles is a high quality app that is simple to use yet provides lots of options. The directions are straightforward and easy to understand, as well as being consistent across the game formats. Players will like competing with friends, so the multi-player feature is a nice touch.

One minor concern is the formatting of the answer numbers in the measurement section. While the problems are clearly written with mixed units (4 feet 5 inches), the answers look as though they are written like fractions (4/5). Some children might find this confusing. Instead, it seems like they could be written in more standard form, such as 4’5” for linear measurement or 5:30 for five hours and thirty minutes in the time section.

### Education

This app provides an outstanding method of putting life into the essential drill and practice that will allow students to become comfortable with computations with fractions, decimals, measurements, and so forth. Every teacher knows that these types of problems won’t truly be mastered until students have done countless examples, and Math Galaxy Fraction and Decimal Riddles is a great alternative to endless paper and pencil drills.

It’s also very nice to have so many levels available in one app. Kids can practice identifying parts of a whole, putting fractions or decimals on a number line, and all four operations with both kinds of numbers. There are sections that provide drill on adding, subtracting, multiplying and dividing both fractions and decimals as well as computing the answers to problems involving units of length, volume, weight and time. In addition, the app includes an “angles” section where students must mentally calculate the measure of the chosen angle using concepts such as complementary and supplementary angles, alternate interior angles and so forth.

### Entertainment

Most kids (and even many adults!) love riddles-and this app is full of them. The riddles activity randomly selects a riddle and poses a set of problems that have letters attached. Match the problem to the solution correctly and the letter will drop into place in the answer, eventually revealing it. If you happen to get a riddle that you’ve seen before, there is a button on the screen to change the activity to a different riddle. The Jumbles section will appeal to word puzzle fans, as well, with scrambled letters that reveal a secret word when matched to their problems. With over 500 riddles and 600 word jumbles available, you are unlikely to run out of fun!

### Value

This app is \$4.99 in the App Store, which may seem a little pricy at first, but by the time you consider the vast range of play activities (suitable for students from grade 3 on up through middle school), and the incredible number of different problems and games, it is a great value. With multi-player capability, it’s also a wonderful addition to home or school.

### Child Friendliness

This app is completely child-friendly with no links to the internet, email, or social media.
