Column Division 1.0 is now available

Independent developer Esa Helttula has released Column Division 1.0, a new educational math app for iPhone and iPod touch. The app can be used to teach and study the column division method.

The column division method is a simple variation of the traditional long division method. Lines are drawn to separate the digits of the divisor. Each place-value column is solved from left to right. The column division method emphasizes the concept of place value and can thus be easier to understand than the traditional long division method. In the Everyday Mathematics curriculum the column division method is one of the algorithms for division.

The Everyday Mathematics Curriculum:
Everyday Mathematics is a new mathematics curriculum developed by the University of Chicago School Mathematics Project. In the United States over 3 million students in 185,000 classrooms are currently using Everyday Mathematics. Parents may find it hard to help their children with the "new math" and apps like the Column Division can help both children and parents.

The Interface Supports Learning:
If the user presses the wrong button the answer will appear above the keyboard but it will not move. "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", said assistant professor of mathematics education Tim Pelton in his review of Column Subtraction, a sister app of Column Division that uses the same kind of input method.

Difficulty can be set with Settings:

  • The dividend can have from 2 to 5 digits
  • The divisor can have 1 or 2 digits
  • The current operation can be hidden
  • The operands of the current operation can be highlighted
  • Colors of the interface can be changed
  • The speed of the animations can be set

Device Requirements:

  • iPhone and iPod touch
  • Requires iPhone OS 3.0 or later
  • 0.4 MB

Pricing and Availability:
Column Division 1.0 is only $0.99 USD (or equivalent amount in other currencies) and available worldwide exclusively through the App Store in the Education category.
