This time, I got to share the results of a lesson that I guinea-pigged on my Honors Precalculus class last year, where they explored the relationships between polynomial sequences, common differences, and partial sums. The presentation from the GMC uses the techniques we looked at to develop the formula for the sum of the first \(n\) perfect squares:

\[1^2+2^2+3^2+\cdots+n^2=\frac{n(n+1)(2n+1)}{6}\]

At the GMC, we did go a bit further than my class did --- they didn't do the full development of discrete calculus --- but some knowledge of where the ideas lead is never a bad thing, and a different class at a different school may even be able to go further!

**Here is the PowerPoint from the presentation.**If you find it useful, or have any questions, please don't hesitate to leave a comment!

*(I recommend downloading the PPTX file and viewing the slide show in PowerPoint, rather than using Google's online viewer.)*
