###### Pros

It's well-organized and offers a reasonable range of concepts, simple layout, and helpful data reporting.###### Cons

Concepts aren't explained clearly and some lack depth, particularly geometry.###### Bottom Line

Offers good learning potential for pre-algebra concepts, despite a few rough edges.Five-second timed quizzes provide a challenge for some but stress for others. Basic design is appealing but could be jazzed up a bit to increase the fun factor. Perhaps some more exciting challenges would draw kids in more.

Kids are gently encouraged to work faster, though flexible bonus time would be a great feature. Kids can choose between multiple-choice or type-in modes. Some directed and responsive encouragement could improve learning outcomes.

Simple layout and comprehensive main menu make navigation easy. The "game over" page gives extensive data, including a link to a bell curve histogram viewable by math concept, level, individual user, or all three.

The guide gives some good, though not entirely polished, tips: Have kids start by taking level A quizzes in operations (and other concepts) they already know in multiple-choice mode, ignoring the time bonus. Allow younger kids to use paper and pencil to work out their answers, but for higher grades, emphasize mental math. Once they've mastered beginner quizzes, you can urge them toward higher levels, mental math, and getting time bonuses.

Fourth, fifth, and sixth graders will benefit from the four operations and next 12 categories; the final seven categories are definitely middle school only.

Read more Read less*Math Pack Flash Cards *is a series of well-organized quizzes (not really flashcards at all) ranging from simple one-digit addition to eighth-grade-level probability. With a simple menu and layout, the app includes multiple-choice or type-in answer modes as well as data reports. A short but sweet guide for parents and teachers is tucked into the About section with how-to hints.

Kids choose from 25 math concepts including operations, decimals, four-quadrant graphing, algebra, and probability. Ten-question quizzes, four for each concept, offer four choices each; type-in mode offers a number pad and buttons for “clear” and “enter.” Even though the five-second bonus timer is small, it adds a bit of stress. The “game over” screen shows total number of correct and incorrect answers, score in percentage, total bonus points, an efficiency score based on speed, percentile rank, and a link to the user forum efficiency statistics.

Read more Read less*Math Pack Flash Cards* is a great way for kids to increase speed and efficiency in math basics as well as advanced middle-school concepts. The built-in time bonus and superb data reporting, including efficiency displayed on the main menu, really give kids a helpful view of how they're doing and how efficiently they work. Downsides: inconsistent and hidden explanations of concepts, lack of depth for some concepts -- particularly geometry -- and relatively basic, dry design. An adjustable bonus countdown quantity would also help provide a bridge for kids who get stressed easily under time pressure.

The "help" explanations accessed through operator and concept icon buttons are not always super useful but worth a look anyway. Overall, kids should already have a good understanding of the concepts -- and an efficient solution algorithm -- before taking the quizzes. Though the main menu has a pleasing and simple layout, A to D rows are a bit confusing at first, and some numbers in parentheses remain cryptic.

5.NF.1 | Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.) |

## Ratios And Proportional Relationships | |

6.RP: Understand Ratio Concepts And Use Ratio Reasoning To Solve Problems. | |

6.RP.1 | Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.” |

7.RP: Analyze Proportional Relationships And Use Them To Solve Real-World And Mathematical Problems. | |

7.RP.1 | Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour. |

7.RP.2 | Recognize and represent proportional relationships between quantities. |

7.RP.2.a | Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin. |

7.RP.2.b | Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. |

7.RP.2.c | Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn. |

Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts. |
