If you have kids you will need to intervene to give them a good math science education.

Fortunately there are some great resources, far better than the average colorful school textbooks :

- aops.com and their BeastAcademy cartoon series

- an old book "Algebra" by Gelfand

- W W Sawyers old books on how math should be taught

- Geogebra and Desmos web tools

- 3Blue1Brown

- KhanAcademy

I try and introduce math in a more visual way, with multipication as rectangles and the distributive rule being central concepts that lead into all other areas of math :
