They say Isaac Newton invented Calculus while quarantining from the Plague. While my dad hasn't reached that level of quarantine boredom, he's devised a really fun and artistic approach for teaching Excel – and yesterday released the first e-book in his "Spreadsheet Adventures" series.
"Coloring Fun with Conditional Formatting" is a step-by-step guide and puzzle collection. It shows how to create beautiful mathematical patterns in Excel, while building up the reader's familiarity with formulas and conditional formatting. In proofreading my dad's initial draft, I thoroughly enjoyed it, and was blown away by the beauty and unpredictability of some of the patterns. I'm including just a few of the images below.
If this piques your interest, you can purchase the e-book here: https://leanpub.com/spreadsheetadventures/.
More info about the Spreadsheet Adventure series can be found on my dad's website: http://spreadsheetadventures.com. And you can also follow him on the Facebook, where he plans to post weekly puzzles and beautiful pictures at https://facebook.com/spreadsheetadventures.
I hope you enjoy it (and if you can think of someone else who'd benefit from the book, please help spread the word :-)).
