Math Division, Multiplication, Addition, Subtraction, Fractions, and Rounding Bundle 4+

This bundle has 10 iDevBooks math apps. Save 62% compared to buying the apps separately.

Long Division

The Long Division app has been featured by Apple in "New & Noteworthy", "Math - Numbers & Operations", and in "Math Apps for Middle School". Educational App Review (iear.org): "This app is fantastic!!"

Partial Quotients Division

The traditional long division method can be difficult to understand because it is so abstract. In the partial quotients method the student can make a series of estimates and then add the estimated quotients together.

Long Multiplication

In arithmetic, long multiplication is the standard procedure suitable for multiplying numbers. The method breaks down a multiplication problem into a series of easier steps.

Partial Products Multiplication

The partial products multiplication method is a two-step process. In the example 39 x 24, each place value is first multiplied separately. The partial products are added and 36 + 120 + 180 + 600 produces the answer 936.

R. Zeni, Ecole Sandy Hill Elementary: "These math apps 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. Being able to adjust the level of difficulty to suit their needs is also very motivating for the students. I am so glad to have come across this great educational tool!"

Column Addition

Tim Pelton, assistant professor of Mathematics Education at the University of Victoria: “Because no wrong entries are allowed the app provides a passive form of positive reinforcement and your child will likely improve in both confidence and competence with respect to the procedure.”

Partial Sums Addition

The partial sums addition method is a two-step process. In the example 764 + 340, each place value is first added separately from left to right. The resulting addition 1000 + 100 + 4 produces the answer 1104.

Wired.com: “Esa Helttula’s apps are all fantastic for math learning and practice, and aren’t cluttered with mini-games, incentives, or annoying music.”

Column Subtraction

Tim Pelton, assistant professor of Mathematics Education at the University of Victoria: “Because no wrong entries are allowed the app provides a passive form of positive reinforcement and your child will likely improve in both confidence and competence with respect to the procedure.”

Fraction Math

The Fraction Math app can be used to teach and study fractions by solving addition, subtraction, division and multiplication problems with fractions step by step. Wired.com: "Quite a useful app for learning many fraction computations."

The Fraction Math app can handle positive and negative fractions, improper fractions, whole numbers and mixed numbers. The user can also reduce the resulting fractions.

The user can input his/her own fractions, mixed numbers, and whole numbers. The app has also an illustrated glossary of the most common terms.

Decimal Rounding

This math app can be used to teach and study the rounding of decimals. You can set your own problems or solve random problems. The decimal numbers can be rounded to nearest whole number, tenth, hundredth or thousandth. They can also be rounded to 0, 1, 2 or 3 decimal places.

Whole Number Rounding

This math app can be used to teach and study the rounding of whole numbers. You can set your own problems or solve random problems. The numbers to be rounded can have up to 8 digits.

Privacy

The apps have no ads or in-app purchases and they do not transmit any data during the operation of the app. The apps also do not contain any links to other apps or the web.
