iDevBooks create Maths apps aimed at our older children. There are no gimmicks, "bells and whistles" or pretty pictures. They are solely for the purpose of teaching the various principals of Mathematics to our children in a way they understand. My son is very bright and understood all maths principals except for division. I tried all ways to explain with no response. One day using iDev apps long divison app and he GOT it! These apps work and we are very lucky to have iDevBooks as our Devloper of the Week. Enter todays giveaway and check back tomorrow

Esa Helttula’s apps are all fantastic for math learning and practice, and aren’t cluttered with mini-games, incentives, or annoying music.
The Partial Sums Method
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.
In the Everyday Mathematics curriculum the partial sums method is the focus algorithm for addition.

This app can be used to teach and study the alternative column-addition method used in the Everyday Mathematics curriculum developed by the University of Chicago School Mathematics Project. The app is easy to use and it has an intuitive interactive interface with customizable colors and other settings.
The Everyday Column-Addition Method
The method is called column-addition method in the Chicago School Mathematics Project but the app is called the Everyday column-addition method to distinguish it from the standard column addition method.
The Everyday column-addition method was developed and shown to the Everyday Mathematics authors by a first grader. The method has two stages. In the first stage the digits are added one column at a time in each column. After the first stage some columns can have two-digit numbers. In the second stage the carries are done to obtain the result.
