Deriving the Quadratic Formula

Deriving the quadratic formula is probably one of the most challenging tasks an Algebra 2 student will have to complete during the year, and without a doubt, one of the most frustrating!

When the day arrives to derive the formula, I tend to make a big deal out of how difficult the day is going to be, how frustrated they will become, and how proud and excited I will be if they don't give up; how proud THEY will be if they come close to the end.  I also give out TONS of encouragement and of course lots of help.

I let students go mostly on their own, with some guided notes to help as they struggle through the class period, and I wander around helping students as they are working and discussing the task with their peers.

Each year, I continue to be amazed as they take on this difficult task, trudge through it, hurt their brains and continue on!  Each year, among and beyond the frustration, there are high fives, congratulations and proud moments of accomplishments!  

**The guided notes with entrance and exit tickets that I use with students are available to fans of my FB page "The e Elephant Loves Math" for FREE (for a limited time only), and can also be found in my TpT store.


  1. Hi,

    I happened to chance upon your blog and found it very interesting!

    We have recently launched a science app that uses augmented reality to enhance classroom teaching. The app has 3D models for kindergarten to grade 12. I thought you might want to check it out and may be review it on your blog, if possible.

    It is a paid app(with a few models free) but in case you are interested in trying it out I will be happy to provide you with a free copy.

    The link to the app is:



    You can also search for the app on the app store as 'Augmenter'.

    Do let me know if you would be interested. I am really Looking forward to your response.

    happy teaching!


  2. Thanks so much for the freebie and your insights! Much appreciated!

  3. I just hate the subject known as Algebra, from my childhood. When I was in 5th grade, Algebra has become the part of our course. I never could understand its formulas and equations also.

  4. I am absolutely loving your gorgeous blog! Thanks
