Reflection: Complex Tasks Conics Sections with Princess the Dog - Section 1: Launch


The most challenging aspect of this task was for students to understand exactly what was going on in the second scenario where Princess could move freely along a leash that is attached at both ends. Students had a difficult time visualizing what this would look like. I am glad that they were talking things over and I think having a model of this would be too leading, but I wish I had a physical model to show at the end of the lesson. I had to rely on a Geogebra animation where I could move a point along an ellipse.

In this photo a student had the general shape of the ellipse but was confused about how to geometrically find some of the points on the ellipse. This student was also confused about the premise and was thinking in terms of a polygon instead of a curved boundary.
