The Bits Go By

On Page One Fifty Three, Sayadaw points out that eye, ear, nose, tongue and body rupa-kalapas can be transparent and all others are opaque.

First, rupa-kalapas will look like lumps, which arise and pass away (but that is not their ultimate reality, it is only three types of illusory compactness), and one should see all of the elements in them.

A Fortress

On Page One Fifty Two, Sayadaw takes a sidebar to point out that jhana can be a helpful place to rest, like a fortress.  He identifies 'pure Vipassana yogis' who have only access concentration and not jhana, who can also do this.

Sparkles

On Page One Fifty One, we have 'How to See Rupa Kalapas'  (the teeny tiniest things).  Basically, the block of ice you are as previously mentioned, will break down into sparkles.  These are them. And once again, not to bum you out if you are just still sitting restlessly and noting restless, but this is the 'beginning of Vipassana meditation.' 

Ice Ice Baby

On Page One Fifty, Sayadaw moves back to seeing 'Ultimate Materiality', beginning with 'seeing the body-transparent element as one block.'  To do so, notice the different kinds of light you see as you meditate on the four elements. This seeing the body as a block of ice or glass is due to not yet seeing through the three kinds of compactness.

Becoming Cool

On Page One Forty Nine, Sayadaw takes 'Ten Ways to Develop Your Concentration" from the Visuddhimagga. They are:

1. Study the elements in sequence; Earth, water, fire then wind. 
2. Don't go too fast, you'll miss something. 
3. Don't go too slow, you'll not reach the end. 
4. Ward off distractions.
5. Go beyond concepts; I love this about meditation, for me it actually makes it easier, to get 'below' or 'let go' of concepts and just be with the object. 
6. Discard what is unclear.
7. Discern the characteristics clearly (and that takes time and effort)
8. Develop your concentration in line with the Higher Mind Sutra
9. Develop your concentration in line with the Becoming Cool Sutra
10. Develop your concentration in line with the Enlightenment Factors Sutra.

The last three are about balancing the five faculties and the seven factors of enlightenment (previously discussed). 

All the Elements

On Page One Forty Eight, Sayadaw suggests some concentration on the opposites of the elements if in this meditation they become unbalanced, the opposites are hardness and softness, roughness and smoothness, heaviness and lightness, flowing and cohesion, heat and cold, support and pushing.

Balancing the elements helps with a major goal beyond seeing and knowing the elements, which is to attain better concentration.
Following their being quite balanced, the yogi should see the elements in the body by 'group at a glance', and finally as a whole, possibly from the vantage point of looking down on the whole body at once.

But the Last Two

On Page One Forty seven, Sayadaw notes that the first ten elements can be discerned directly through the sense of touch, but flowing and cohesion can only be inferred from them.

For cohesion, note how the body is held together by the skin, flesh and sinews.  For flowing, be aware of saliva, blood, air or heat.
