This is the first section of a self-paced course where students learn to add and subtract on the abacus. It is a great starting point for kids to get acquainted with the abacus. By the end of this section, students should be comfortable reading numbers on the abacus and performing simple direct movements. They first get experience with the bottom 4 beads and then incorporate the top bead to sum up to 9. When they have mastered these skills they can move on to Part 2: The Pull-5 and Break-5 Movements.
