This is a lesson plan that I created on Imaginary Numbers. This lesson will teach students what imaginary numbers are and why they are relevant.
This lesson teaches students about the 5 triangle congruence theorems as well as the donkey theorems, which do not prove the triangles congruent. In this lesson, students will be using the NCTM illuminations website in order to visualize the parts of triangles and see why the theorems are either true or not true.
This lesson plan is meant to take several class periods. It is a webquest designed to make students think about parabolas in the real world. The students will work in groups to first find information about real life parabolas and then to discuss the variety of methods used to solve quadratic equations. I have included the PowerPoint lesson in the next section.
Here is the actual Webquest that was discussed above.
