Children are absolutely amazing and they are always surprising you. They are extremely intelligent and most of them are seeking ways to please their parents and show how skilled they have become.
I was teaching and practicing writing with my son and he took the pencils, the pen and ruler and said to me: "Mom look, it's a square"!!!
He even went further and said: "I can also make a triangle"!!
He was very proud of himself for replicating the things I have taught him and also to see me pleased with his initiative and success.
This is an example that investing in our children's future and education is valuable, and nothing that we teach is wasted.
