Wow, what are they doing? :) Are they......?
Yes, they are treading beads by using shoelace.
We realize they are so patient, so careful when they are doing this activity.
This activity not only train them to be patient but also train their hand eye coordination.
So maybe you want to try with your children at home?
when they are throwing tantrum, try treading activity.
But parents must also make they are just beside the children, so that the children will not swallow the beads.
