Big Math

Read full description

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! Dolphin sounds are courtesy of Dolphin Encounters in the Bahamas! Try it and enjoy!
