Would you correct some of the mistakes in my writong?

I will tell you about my family.

There are four people in my family.

They are my dad, my mom, my sister, and me.

My dad is a computer programmer. He came home in the evening, but sometimes he came home late because he is busy. He is good at math.(?) My mother is a professor. She teaches students computer. My sister plays at the kindergarten. She studies and plays with dolls at home. She likes dolls and hairpins. I go to school and study. After school, I go to English and 태권도 academies. I like to go to parks and play.
