OneTab Chrome Extension

The OneTab Chrome Extension ( is typically recommended as a way to free up processing speed and reduce clutter when attempting to have a tab-tervention with a tab-crazy browser user.  And, well, that’s a true, but it doesn’t tell the full story of OneTab . . .

OneTab is actually a fantastic option for organizing, categorizing and sharing the sites that we mean to look at, read or follow up on, but just don’t have time – as well as ones that we intend to come back to repeatedly. Think of it as your website to-do list manager.  Check it out in the video below.

Pro Tip: At the school that I work at, our students are doing Passion Projects.  Each week, they have to reflect on their progress and growth in a Google Doc.  For 12 of the kids, I’m tasked with looking at that reflection weekly and providing feedback.  So, I keep the links to their reflections in a locked OneTab Group.

Proving the Algorithm for Mean (Average) in Google Sheets

I am a huge spreadsheets nerd and a huge advocate of the use of spreadsheets in mathematics instruction.  If you keep an eye on my site (or Twitter feed or YouTube Channel) you’ll see plenty of my reasons why I feel this way.  Here’s one:

Spreadsheets are a great tool for proving mathematical algorithms and formulas.  In this post . . . how we can use a Google Sheet to prove the formula for the mean (which, in spreadsheet land, is known as the average).
