I taught myself to recognize five as a distinct quantity. Useful when counting up the "spare change jar".

I assume you see 3 objects on a table as a triangle. It's probably not equilateral, but any three objects on a table describe a triangle.

Make sure you can see 4 as a square, not 2+2. If you're stuck on seeing two pairs (or lines), try seeing 3+1 (a triangle and a point) instead. Then incorporate the point into the triangle...

Next, see pentagons. ... That's it.

I haven't tried to see "six"... Five was hard enough. :P
