1. Venn Diagram — Brain-Level Explanation

A Venn diagram is a picture of logic.

• Circles = sets
• Dots / shaded area inside = elements
• One circle inside another = subset
• Overlapping circles = common elements

Neurological hook

The brain understands space faster than symbols.
So when a student sees one circle fully inside another, the brain instantly reads:

“Everything here belongs there.”

That is exactly what subset ( ⊂ ) means.
