ABACUS: MYSTERY OF THE BEAD
Abacus or Abaci is an ancient Asian calculating tool that helps modern students as young as age 4 or 5 master essential math skills they will retain and use all their lives. There are many different types of Abacus and different terminologies are used around the world. We will be using the phrase called “Japanese Soroban” in this program.
