Engagement
Is the product stimulating, entertaining, and engrossing? Will kids want to return?
4
Graphics and rewards pull kids in, and the variety of interactive games should keep them going.
Pedagogy
Is learning content seamlessly baked-in, and do kids build conceptual understanding? Is the product adaptable and empowering? Will skills transfer?
3
Students play games to practice skills and then apply what they practiced to solve higher-order thinking problems. The reward system is motivating but could distract some kids from learning.
Support
Does the product take into account learners of varying abilities, skill levels, and learning styles? Does it address both struggling and advanced students?
4
Not all the games are intuitive, but animated instructions help. Instructional feedback for incorrect answers, at least at the training skill level, would improve support.
How Can Teachers Use It?
Teachers can use Zap Zap Math for targeted practice in the classroom. The games align very well with Common Core math standards and could serve as a pre-assessment tool, giving kids practice before a high-stakes exam. Choose a standard to practice from the appropriate grade level, and then choose a skill. Have kids complete a skill and track their progress on the teacher dashboard. Instructional feedback is not built into the games, so teachers need to provide their own remediation if needed.

What's It Like?
Kids start playing Zap Zap Math games by selecting a grade and a skill: training, accuracy, speed, or mission. The games default to the first set of Common Core standards listed, but these can also be selected before playing a game if kids want to practice a specific standard. Each skill takes a different approach on a standard, with the mission skill being the most challenging. In this skill, kids must apply what they've learned to complete a task. A web-based teacher dashboard allows for progress tracking once kids enter a code from the app.
For each level within a skill, kids earn points and rewards they can use to decorate rooms inside a spaceship. It's always nice to have motivating rewards, but the reward window pops up after kids complete a level. This, along with the frequently busy screen, might distract some kids who just want to get stuff.

Is It Good For Learning?
With Zap Zap Math, kids can learn about many concepts covered by Common Core math standards. These standards are sometimes hard to break down into meaningful, kid-friendly lessons, but the app does an excellent job of addressing this challenge; kids could benefit from the practice that the games provide. Having four skills within the same set of standards is also a great way for kids to deepen their understanding of the standards. Since kids do not receive instructional feedback for incorrect answers, it's important that teachers use the dashboard to monitor progress and provide reinforcement as needed.
The game is filled with lots of bells and whistles, which could be engaging and motivational to some kids. However, the constant music and reward and purchase pop-ups are a bit much. The graphics are fun, but some take a while to load. Overall, Zap Zap Math offers plenty of practice for kids who are trying to master Common Core math standards.

For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ... |

If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie? |

For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8. |
| 3.OA.4 | Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = � ÷ 3, 6 × 6 = ?. |
| Understand Properties Of Multiplication And The Relationship Between Multiplication And Division. | |
| 3.OA.5 | Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.) |
| 3.OA.6 | Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. |

| Solve Problems Involving The Four Operations, And Identify And Explain Patterns In Arithmetic. | |
| 3.OA.9 | Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends. |
| 4.OA: Gain Familiarity With Factors And Multiples. | |
| 4.OA.4 | Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite. |
| Generate And Analyze Patterns. | |
| 4.OA.5 | Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way. |
| 5.OA: Write And Interpret Numerical Expressions. | |
| 5.OA.1 | Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. |
| 5.OA.2 | Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product. |
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.” |
| 6.RP.2 | Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar.” “We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger.”1 |
| 6.RP.3 | Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. |

| 6.NS: Compute Fluently With Multi-Digit Numbers And Find Common Factors And Multiples. | |
| 6.NS.4 | Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2). |
