If you enjoy vocabulary items you'll probably get pleasure in the word subitize. Some elementary school teachers now use that concept. It's the ability to immediately perceive how many objects you're looking at without counting them. Those who know constellations also subitize as well. When we see Orion, the three belt stars are an obvious formation; we don't have to count one-two-three to determine if they are hidden behind a cloud.
