(1) The document outlines topics from the first lecture in a geometry and measurement course including the syllabus, grading, Canvas, the National Council of Teachers of Mathematics (NCTM), teaching methodologies, the van Hiele levels of geometric thinking, and an introduction to geometry. (2) Students are instructed to take notes on important topics from the lecture and the professor will assess their notes. Key course documents and how to access help resources through Canvas are also reviewed. (3) The van Hiele levels are introduced as a framework for understanding students' geometric thinking at different stages from visualization through rigorous logic and proof.
