Why a single feed doesn't work for lesson prep
Lesson prep is not casual viewing. When you sit down to find a video for tomorrow's class, you usually know the subject and roughly the grade level you need — but YouTube's default subscription feed ignores both. It shows you everything you subscribe to, in upload order, regardless of whether it is useful for the lesson in front of you.
Two problems come up especially often for teachers:
- Subject mixing. A biology channel's new upload sits next to a channel about the Cold War, which sits next to a channel for a grade you do not currently teach. None of it is grouped by what you would actually reach for during prep.
- No separation between 'maybe' and 'yes'. Channels you are still evaluating for classroom use end up in the same list as channels you already trust and use every week. There is no way to tell, at a glance, which is which.
A starter folder structure for teachers
Use FolderTube to create folders that match how you actually search for material. A structure that works for most classroom subjects:
| Folder | What goes inside |
|---|---|
| Math | Concept explainers, worked-problem channels, math practice content |
| Science | Demonstrations, lab safety, explainer channels by discipline |
| History & Social Studies | Documentaries, primary-source walkthroughs, current-events explainers |
| Language Arts | Literary analysis, grammar and writing channels, author interviews |
| Under Review | Channels you found recently and have not yet decided are classroom-ready |
| Classroom-Approved | Channels you have actually used with students and trust for reuse |
Adjust the subject folders to what you teach — an elementary generalist might use one folder per subject the way above, while a single-subject high school teacher might instead split by unit or course. The Under Review / Classroom-Approved pair is the part worth keeping regardless of subject, because it solves the 'is this actually good' problem separately from the 'what subject is this' problem.
Setting up the folders
- Install FolderTube from the Chrome Web Store.
- Open YouTube and click the purple FolderTube button in the top-right of the page to open the sidebar.
- Press the sync subscriptions button to import your subscribed channels.
- Create a folder per subject, plus an Under Review and a Classroom-Approved folder, and drag each channel into the one that fits best.
- Open the Subscriptions page and use the folder tabs to view uploads one subject — or one review stage — at a time.
Add real folders to YouTube
FolderTube is free to install. Drag your subscriptions into folders and finally find what you actually want to watch.

The weekend prep session
Open the folder for whatever subject you are prepping next. Since a channel can only sit in one folder, everything you see there is on-topic for that subject — no scanning past unrelated uploads to find what you need.
New channel triage
When you find a promising channel — from a colleague, a search, or a recommendation — subscribe and drop it straight into Under Review rather than a subject folder. Only move it into a subject folder once you have actually watched enough of it to trust it in front of students.
Grade-level transitions
If your teaching assignment changes grade levels or courses between years, this is the moment to revisit your subject folders. A channel that was perfect for last year's grade level may not fit the new one — move it out rather than letting it sit unused.
Using Mark as Watched during video vetting
Vetting a video for classroom use often means watching part of it, deciding it is not quite right, and moving on — only to open the same folder next week and not remember whether you already checked that one. The Mark as Watched feature grays out the thumbnail and adds a checkmark once you flag a video, so your next pass through Under Review only shows videos you have not yet evaluated.
This is useful regardless of whether the video ended up approved or rejected — marking it just means 'I have already made a decision about this one', which is exactly the information you want when you come back to the folder later.
Going further: subfolders by unit or grade
If a subject folder grows large enough that scanning it takes real time, subfolders — a Premium feature — let you split it without losing the top-level grouping. A Science folder could split into Biology / Chemistry / Physics; a History folder into the units you actually teach across the year.
Premium starts at $2.99/month, with $19/year and $39 lifetime options. It also unlocks custom folder colors and icons, which is a small but real time-saver if you have several subject folders open in the sidebar at once.
Keep a paper trail outside YouTube too
Folders organize which channels you watch, not which specific video you used with which class. For videos you plan to reuse year after year, note the title and link in your lesson plan document as well — folders make finding a channel fast, but they are not a lesson-plan archive.
Maintenance habits
- Clear out Under Review at the end of each grading period. Channels sitting there for months without a decision are usually a 'no'.
- When a channel changes its focus or your curriculum changes, move it out of Classroom-Approved rather than leaving it to go stale.
- Revisit subject folders each time your teaching assignment changes — new grade, new course, new subject.
