Description

SpinCalc™ is a unique children's calculator that feels like a game, but teaches children what arithmetic really means. Kids enter the numbers by simply spinning the wheels. If the wheels are set to 9 and 3, you see:

• Addition: 9 + 3 = 12

• Subtraction: 9 - 3 = 6

• Multiplication: 9 x 3 = 27

• Division: 9 ÷ 3 = 3

SpinCalc has no keyboard - just two wheels to spin, which makes it easy and fun for kids.

Dots TV™:

The educational value comes from "Dots TV", shown in the screen shots. The TV channels show little boxes that illustrate the actual results of a calculation. For example:

• Addition TV shows 12 color-coded dots for "9 + 3"

• Subtraction TV shows 6 green dots for "9 - 3", but 6 red dots for "3 - 9".

• Multiplication TV shows 27 dots (9 rows of 3 dots each) for "9 x 3".

Multiplication tables come alive with Dots TV. Where else can your child actually see the results of 9 x 12 as 108 little boxes? Do you know how big 2, 000 is? Multiply 40 x 50, and see 2, 000 dots appear on the screen.

Simple For Young Children:

You can simplify SpinCalc for young kids by turning off various features, including:

• Addition

• Subtraction

• Multiplication, or

• Division

• Zero (so only numbers from 1 to 50 appear on a wheel)

• Numbers up to 10, or up to 50
