If a student allows here is a long lasting way to teach math 

1. Play chess - to teach focused thinking

2. Practice calligraphy - for being present

3. Practice synonyms - for intelligence

4. Paint long chains with links - to understand derivations

5. Read fiction - to know why do this at all (abstraction)

Play is a good thing. 
So is Math. 
Neither needs a reason. 
So on with both.

Deep immersive introspection. 
Hearth of creativity.
