In this tutorial, I’m walking you through how I use conditional formatting in Google Sheets to run quick checks with my students—without adding a bunch of extra steps to my workflow. If you’ve ever wanted a fast way to see who’s got it and who needs a quick reteach, conditional formatting is one of those simple teacher moves that makes your spreadsheet do the thinking for you. I show how conditional formatting can automatically highlight responses based on rules you set (like correct/incorrect, above/below a target, or matching specific text). The big takeaway is that you can set up these visual “at-a-glance” checks so you’re not manually scanning every cell. Once it’s in place, you can reuse the same sheet structure again and again for warm-ups, exit tickets, or quick practice—making Google Sheets a lot more classroom-friendly for real-time feedback.
