Addition using the abacus!

A few students noticed the abacus on the shelf and asked if they could play with it. As they explored the beads by moving them back and forth on the row, they naturally stared counting them! I asked them to grab some paper and markers and draw and write what they were doing.

They were very proud when they shared their work with the class. They demonstrated counting the beads to get the total number.

I wonder what new ways of adding with develop?!
