What is an Abacus
The Abacus is one of the first counting tools. It was used centuries before the modern number system was even invented. It is technically the first computer. A computer is a device that stores and processes data. Data is the raw value that becomes information when meaning is given to the data.
You will be building your own binary abacus using popsicle sticks, beads, and pipe cleaners.
You will use pipecleaners to hold the counting beads together in a popsicle stick-frame. The top pipe cleaner has 1 bead, that is the digit on the right part of the number, just like the 1’s place in decimal, this is also 20. The next position to the left in decimal is the 10’s place, that each value is 10 times that value, in binary you have 2 beads, so you either have a value of 2 or zero coming from that spot, this is also 21. The next spot to the left is the 100’s place in decimal, in binary this place is worth zero or 4, this is also 22.
This pattern will continue as you add more values to the left, with the value you get from that spot doubling with each position. Once you know your values from every position in the number, you add them together, just like you would in decimal. A picture of what your binary abacus will look like is depicted below
