Long Multiplication vs Big Math

Long Multiplication helps students learn and practice the standard long multiplication method step by step. The app shows each part of the long multiplication process visually. Students multiply and add one step at a time, and animated numbers move into the correct places. This makes the column method easier to understand and practice. Long Multiplication can be used for classroom teaching, individual practice, tutoring, or homework support. Problems can be generated by the app or entered manually. Features: - Step-by-step long multiplication practice - Multiplicand can have up to 5 digits - Multiplier can have up to 4 digits - Supports decimal numbers - Students can enter their own problems - Current operation for each column can be hidden - Operands for the current operation can be highlighted - Five visual themes - Native interfaces for iPhone and iPad Reviews and Recognition: Reviewed by Wired.com as part of “A Set of Excellent iPhone Math Apps for the Older Child.” Teacher endorsement: “The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.” — Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada Kelly Tenkely, iPad Curriculum: “The step by step animation and guidance will help students get the column method of multiplication down in no time. The ability to enter their own numbers means that students can input problems from a math curriculum or textbook and work through the step-by-step process with any problem.” Other iDevBooks Math Apps: Other iDevBooks math apps include Column Addition, Column Subtraction, Long Division, Lattice Multiplication, Visual Multiplication Table, Fraction Math, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, Decimal Rounding, and more.

Big Math is an iPad app for elementary school children to practice addition, subtraction, multiplication and division of big numbers. It has both portrait and landscape orientation. It has a dolphin theme, and when the child has finished a set of problems, a dolphin sound (whistle, scream, yell or motorbike) is heard. The child starts by picking what he or she wants to work on in the Settings screen of the app. Settings options include: * Entering a name and message for the child who will be using the app. The name and message show up throughout the app. * Entering the options for addition, subtraction, multiplication, and/or division. For addition, the child can add 2 numbers, either 2 digit or 3 digit, or 3 numbers, either 2 digit or 3 digit. For subtraction, the child can subtract either 2 digit or 3 digit numbers. For multiplication, the child can multiply 2 digit or three digit numbers. For division (long division), the child can divide with a 1 digit, 2 digit, or 3 digit divisor. The app allows regrouping, where the child can "carry" in addition, multiplication, and division or "borrow" in subtraction and division. The child can elect to have problem sets timed. Once the settings are set, the child goes to the area he or she wants to practice (Big Add, Big Subtract, Big Multiply, or Big Divide), selects the number of problems to do, and starts doing Big Math!
