My First Calculator app for iPhone and iPad

My First Calculator is a great way to introduce numbers, counting, addition, subtraction and basic features of a calculator to children. It has been designed to focus on core introductory numeracy competencies before introducing children to further concepts such as zero and negative numbers.

FEATURING
* Visually concrete representations
- A narrated voice reinforces the number selected. This is followed by a cute sound effect that enables mental referencing
- Animals are shown randomly for every equation

* Equation bar
- Watch the equation update dynamically increment as numbers and operators are selected

* Errorless teaching
- My First Calculator brings children through a step by step process by allowing only permissible buttons to be pressed. E.g. You cannot press the Plus (+) button without first pressing a number.

* Zero comes later!
- Avoid the confusion of zero concepts when introducing numbers. Without the 0 button, My First Calculator allows addition and subtraction up to 18.

* Negative numbers?
- My First Calculator avoids the concept of negative numbers by only allowing subtraction of numbers smaller than the first selected number.

* Realistic button sounds
- Tap a button and hear it pop!
