Reflection: Adjustments to Practice Fluency with Pythagorean Triples - Section 1: Launch

 

If students are always given questions that show the most obvious and customary cues, they will only become good at answering recall questions. I believe this, so, I think it's important to give students practice in taking learned content and using it in unfamiliar situations. 

The launch task in today's lesson, although simple, is more of a knowledge transfer question than a knowledge recall task for my students. To succeed, my students must adapt what they know to an unfamiliar problem. The 3-dimensional figure is not a prototypical right triangle, so my students need to construct an image of the right triangle in order to solve the problem.  

My goal in beginning the lesson with this task is to assess the ability of my students to apply the Pythagorean Theorem.  Of course, I also want to prepare my students for future testing. 

I try to remind myself regularly that I should always try to present questions and tasks that go beyond simple recall, where students show solid evidence of understanding. In class, this means that I need to pay careful attention as the students work in order to know how they arrive at their answer to the task.
