The Babakus is a calculator that combines the best qualities of the western slide ruler with those of the eastern Abacus. It's part of a method for students with dyscalculia or math disability. You can easily work with addition, subtraction, multiplication and division using the Babakus. Although the focus of the method lies on those who find it difficult to deal with numbers and figures, the Babakus is an excellent proficiency training tool for those adept at counting as well. The method is highly scalable to fit each student's level of skill and understanding.
Babakus consists of a number of slide rulers and two counting strips, one for addition and one for subtraction. These counting strips are also used to multiplication and division.
The basic principle is easy; you count using the slide rulers and read the results with the counting strips.
The Babakus is a tool developed by neuropsychologist Björn Adler, spurred by the concrete need for a method for working with numbers and figures, where the student has trouble quickly and easily handling these numbers and figures.
There are three different modes of operation; three, five or seven slide rulers. When using three slide rulers, one may work with five digit numbers.
At the bottom of the Babakus are three icons. A "Home" button, "Instructions, "Training program".
Under "Instructions" you will find a short tutorial of how the Babakus works and how to use it for basic arithmetics.
"Training program" presents you with the step-by-step exercise programme, featuring training on seven levels of difficulty.
Here you can also access the e-book "What is dyscalculia?" by Björn Adler, to further your studies in the field of dyscalculia.
Under "Settings" you can ● add simple mathematical symbols ● define units - either pre-defined units or user defined
The "Home" button returns you to the Babakus
When using the Babakus regularly, a student can swiftly achieve significant improvements. Each digit in a number is displayed using the slide rulers. When adding two numbers together you use the counting strip intended for addition which ranges from 0 to 9. First the single digits are added, then the tens. The Babakus makes the transitions from ones to tens, or from tens to hundreds, very simple. The slide rulers and the counting strips do all the work. The student gets a powerful, clear visual support which helps her to stop counting on her fingers.
