## Reflection: Real World Applications Sequences, Spreadsheets, and Graphs - Section 1: Opener: Make these Column Headers in Excel

Despite their label as a constantly-connected generation, I'm always surprised to see how uncomfortable many of my students are using "serious software" like Excel.  That's exactly why this lesson is essential.  If a student's knowledge of computers begins and ends with social media, touch screens, and watching videos online, then they're really missing out on a lot of what makes a computer such a powerful tool.  With plans in the pipeline for the exams that assess students on the CCSS to be administered on computers, we cannot take it for granted that all of our kids will be ready to use the testing software just by virtue of being raised in a digital world.

Many of my students need me at their side as they learn keyboard shortcuts, or how to hold the CTRL key while clicking columns to highlight a set of data.  "Clicking and dragging" can be awkward for some kids, and many get frustrated quickly.  That's the deeper meaning of the "digital divide".  Most Americans have access to digital tools, but do we all know how to use them in deeper ways?  How many of us can use a computer, not just to consume media, but to make decisions and to create?
