Speakin’ Calc is a great way to introduce your kids to math – or just keep your children entertained. Brightly colored buttons encourage your child to tap them, and the sounds each button makes keep them entertained and engaged. The clear button even causes the iPhone to vibrate as the calculator display is reset.

Speakin’ Calc will speak the calculations your child enters back to them when they tap the equals button. Each tap of a button on the calculator is spoken which helps them associate the roman numerals with the English pronunciation of each number or mathematical operator.
