As almost all schools go Google, one thing you might take for granted is the use of YouTube and your own YouTube Channel. YouTube is a great place to collect resources from all over to introduce topics or review content.
First thing you need to do to create a playlist is find a video.
This is one of my favorite videos (you can watch it here) to play before we begin our section on unit rates. I won't give students the question, but just let them watch the video. We will watch the video again with this in mind, "How many claps does he get in per second?" or "How many could he do in 5 minutes?"
It could be a bell-ringer for an Algebra 2 class or an extension activity for middle school. It is a great math video.
So, you found a video.
Now you need to click the "Add to" button below the video.
Next there is an option to add to playlist.
You can create a playlist or once you have created one add to the playlist you want to add to.
Here is the link for my math video collection: https://goo.gl/2aqJJM
The videos I add range from The Opposite of Infinity by Numberphile which offers higher level math videos to Practicing Free Throws to Beat a Pro by BuzzFeed.
I encourage all teachers to use their free YouTube channel with their school Google account. It is a great place to collect resources to use in your classroom.
