How many ways can you graph a quadratic? The video shows two approaches to graphing a quadratic expression that is initially in standard form. The first method finds the vertex using -b/2a. The second approach is to find (h,k).

Instructional Ideas

• Use editing software such as EdPuzzle to insert questions periodically throughout the video for pupils to complete
• Post the video as a resource for absent class members or those that need extra instruction

Classroom Considerations

• Requires Internet access to watch YouTube videos
• The method used for finding (h,k) is abstract; this may not be the typical method pupils learn
• The lesson is 13th in a series of 29

• This video is hosted on YouTube

Pros

• The author uses multiple methods to accomplish the goal of graphing the quadratic function

Cons

• The lesson does not connect the graph to the transformations from the parent function
