Why mom and dad are better teachers?

1. You know your child's strengths and weaknesses better than anybody else.

2. You are their first teacher. You taught them basic life skills. 

Did you visited a specialist to teach them how to walk, talk , eat, sleep ....?

3. A child is happiest while studying with loving parents.

You can teach them according to their schedule. 

In between give them breaks to play or do some other fun activity in between studies.

This is not at all viable in a coaching/tuition class.

4. As a parent you can adapt teaching strategy to suit your child's interest.

For example, a child who is interested in drawing  can be taught maths concept using drawing.  

Or a child who does lot of chef role play can be taught concepts using kitchen supplies.

5.  Last but not least, you can do a lot of play way learning at home than at school or extra classes.  

Your home is like a big laboratory, give your children freedom to experiment with lots of stuff available at home.

You just need to look around house carefully and you will find stuff that you can leverage for interactive teaching of maths/science and other subjects.
