## Key Standards Supported

## Arithmetic With Polynomials And Rational Expressions | |

HSA.APR: Perform Arithmetic Operations On Polynomials | |

HSA.APR.1 | Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials. |

## Creating Equations | |

HSA.CED: Create Equations That Describe Numbers Or Relationships | |

HSA.CED.1 | Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions. |

## Expressions And Equations | |

6.EE: Apply And Extend Previous Understandings Of Arithmetic To Algebraic Expressions. | |

6.EE.2 | Write, read, and evaluate expressions in which letters stand for numbers. |

Reason About And Solve One-Variable Equations And Inequalities. | |

6.EE.5 | Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true. |

6.EE.6 | Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. |

8.EE: Analyze And Solve Linear Equations And Pairs Of Simultaneous Linear Equations. | |

8.EE.7 | Solve linear equations in one variable. |

8.EE.8 | Analyze and solve pairs of simultaneous linear equations. |

## Reasoning With Equations And Inequalities | |

HSA.REI: Solve Equations And Inequalities In One Variable | |

HSA.REI.3 | Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters. |

HSA.REI.4 | Solve quadratic equations in one variable. |

## Seeing Structure In Expressions | |

HSA.SSE: Interpret The Structure Of Expressions | |

HSA.SSE.1 | Interpret expressions that represent a quantity in terms of its context. |

HSA.SSE.2 | Use the structure of an expression to identify ways to rewrite it. For example, see x4 – y4 as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2). |

## ProsStudents get encouraging words at each step. |
## ConsYou can't track how students are progressing, or if they're progressing at all. |
## Bottom LineAlgebra Touch breaks equations down into steps and describes them with such basic language that math-challenged students should improve. |

##### Learning Scores

In this positive, low-stress algebra intro, kids get encouraging words at each step of an equation and access problems in many ways. The screen only wiggles at wrong answers, so kids are encouraged to try again.

Critical-thinking skills will help kids clarify what's happening and reflect on how each step will, or won't, lead to the right answer.

The user interface lists lessons in order of difficulty and provides clear direction. It's so well-organized, you don't need a tutorial.

For students new to algebra, or any teen struggling to understand the concept, *Algebra Touch* teaches the basics step by step. They'll learn addition, variables, basic equations, negatives, and more, with a total of 20 topics.

Most lessons build on each other, and many appear to assume students know little to nothing about what's being presented, which is helpful: Each step is explained in the simplest of terms. Overall, *Algebra Touch *is an innovative way for students to practice algebra and build concepts, and a remarkably stress-free way to learn.

First, students choose a lesson. Then, a basic problem related to that lesson appears with a written explanation. Along with the written explanation comes an instruction ("Tap the +") telling kids what to do to make the answer appear. Kids then start the lesson, but they aren't expected to enter the final answer. Rather, they tap the steps involved, and then the app gives the answer. Talk about stress-free! At every step kids hear, "Very good!", "Wonderful!", or "Good job!" If they tap incorrectly, the image simply wiggles, encouraging them to try again. When they choose correctly, the next step appears, and finally kids arrive at the answer.

Lessons can be simple. In one addition lesson, kids drag and rearrange single-variable polynomials so like terms are together for easier adding. Practice problems -- which students can save -- are built into the lessons, too, and users can add more.

We might suggest more detailed instruction for new or pre-algebra students, as well as more complex levels for advanced students, but for most teens, this should help them improve understanding and provide that unicorn in math: positive reinforcement.

Read More Read LessUsing *Algebra Touch* on their own, students should learn the basic steps of algebraic equations. But the app can also reinforce skills such as following visual directions, applying information students have learned in class, and identifying strengths and weaknesses in their understanding of algebra subtopics. One bonus is that teachers can use the app as an instructional tool in lessons for the entire class via AppleTV. A downside is that you can't track students' progress, so unless you're watching them work through the lessons, you can't tell who's catching on and who might need more help.
