Improve teaching of estimation.
Tweaking current practice, and exploring potential
Estimation is widely taught, K-graduate. But current best practice has some
crippling gaps. But easily fixed ones. Beyond them, appears an opportunity for
rough quantitative understanding to pervade content and learning.

My focus
Teaching estimation? Use bounding.
Bounding (aka range-based estimation) appears to have much better social dynamics than point estimates, K-graduate.
Teaching estimation? Use landmarks.
Explicitly teaching landmarks (aka referents) permits using estimation on a much broader range of topics.
Rough-quantitative... active learning?
Rough-quantitative reasoning might provide a medium for collaborative inquiry and non-toy analysis, and thus for misunderstanding pruning and play. This would require uncrippling estimation best practice, K-graduate. And creating rough-quantitative descriptive content.
